Q: Type 'undefined' cannot be used as an index type I am trying to convert a function from Javascript to Typescript but I keep running into the following error:
Type 'undefined' cannot be used as an index type
I understand that undefined cannot be used as an index, but I have tried the null check for the index type as well as conditional rendering but nothing seems to work.
Here is my code:

useState hook of values I am using for the function

const [newUser, setNewUser] = useState({
    firstName: "",
    lastName: "",
    companyName: "",
    email: "",
    password: "",
    id: ""
  });

const [errorMessage, setErrorMessage] = useState("");

function which is essentially taking the newUser initial values, making a copy of that object, then calling setNewUser to populate the fields entered by the user into a newUser copied object.

const setValues = (propName?: number, value?: any) => {
        const cloneUser = { ...newUser };
        cloneUser[propName] = value;
        setNewUser({ ... cloneUser });
        setErrorMessage("");
  }

My main issue is the cloneUser[propName] cannot be undefined and used as an index and I'm not sure how to get around this.

A: Answer
Redefine the setValues function as:
const setValue = (propName: keyof typeof newUser, value: string) => {
  // your update code here
}

The parameter types are changed to match your state type, which is inferred as:
{
  firstName: string;
  lastName: string;
  companyName: string;
  email: string;
  password: string;
  id: string;
}

Alternatively
Specify the type for state:
type User = Readonly<{
  firstName: string;
  lastName: string;
  companyName: string;
  email: string;
  password: string;
  id: string;
}>;

// in the component
const [newUser, setNewUser] = useState<User>({
  // initialize here
});

and define the function as:
const setValue = (propName: keyof User, value: string) => { ... }

Explanation
The propName cannot be a number | undefined, since it is used to index an object with string keys (your state). It has to be a string.
The problem that you are facing is caused by the propName parameter defined as propName?: number.
This (propName?: number, value?: any) => { ... } is equivalent to (propName: number | undefined, value: any | undefined) => { ... }. This means that in your setValues function propName could be undefined, which is correctly detected as an error, as undefined value cannot be used to index an object.
Suggestions
I would also suggest to change the name of the function to setValue, as you are only setting one given property at the time.
Additionally, you are setting string values, so the value can also be non-optional and typed as string.

A: Looks like you're trying to arbitrarily add a key value pair to this object with a numeric key and any value. You need to tell typescript that this is allowed by defining a type, and passing it to the generic parameter of useState.
demo: https://stackblitz.com/edit/react-ts-mpdukw?file=App.tsx
type User = {
  firstName: string;
  lastName: string;
  companyName: string;
  email: string;
  password: string;
  id: string;
  [key: number]: any; // This lets you add a numeric key with any value
};

  // generic parameter defines the type of `newUser`
  const [newUser, setNewUser] = useState<User>({
    firstName: '',
    lastName: '',
    companyName: '',
    email: '',
    password: '',
    id: '',
  });

Then, it doesn't make sense to allow an undefined key, so make that property mandatory:
  const setValues = (propName: number, value?: any) => {
    setNewUser({ ...newUser, [propName]: value });
    setErrorMessage('');
  };

Depending on the use case, you may want to allow an undefined key and just skip steps in that case.
  const setValues = (propName?: number, value?: any) => {
    if (propName) setNewUser({ ...newUser, [propName]: value });
    setErrorMessage('');
  };


Increase the value of your home with these simple yet super fun DIY projects pretty much anyone can do!
Have you just found out that you're going to have a few free days in the near future? This is truly a rarity, so you should definitely put your free time to good use. And of course, there are numerous ways to do just that! Performing a simply do-it-yourself project will prove to be a great choice. With DIY projects, you'll be able to do something constructive, while also increasing the overall value of your home. Of course, some activities are going to be more difficult than others. Stick with the projects below and you shouldn't have much difficulty!
Eventually, the items in your home are going to become worn out, old, and slightly boring. When this happens, you should consider making a change. During your free time, you should consider swapping out that ceiling fan that you've begun to despise so much. In general, changing a ceiling fan or light will require two people. You'll need someone to help you hold the light, until you can get it wired up and what not. Nevertheless, this is a simple project that almost everyone can accomplish!
Just remember to shut off the power, before you begin fidgeting around with those wires.
Another excellent project is creating a walkway to your home's entry. Walkways can be made with nothing more than paves, rocks or gravels. Just head to your local hardware store and purchase a good quantity of pavers. Once you've returned home, you can begin laying out the pavers however you like. This is truly one of the most simplistic DIY projects and you can complete it without any helpful. You may need a shovel, so you can level out certain areas, but this project truly couldn't be easier.
If you really want to get creative, you should consider installing a fountain. Your options are plentiful. You can stick with a traditional fountain or you can opt for one of the innovative outdoor water fountains for the wall. Both options will be surprisingly easy and you'll likely be able to get the job finished within a day! The only problem is that you're going to need a water pump. Today, you can choose between electric pumps and solar powered pumps. Both work exceptionally well, but the solar models provide more convenience and can also help you save money!
As mentioned above, everything in your home is going to grow boring eventually. This includes your lights, floor and your walls. Thankfully, the wall problem can be rectified very easily. Almost everyone in the world has painted a wall at least once or twice in their life. It truly couldn't be easier. Just head to your local home improvement store and acquire the paint color of your preference. Make sure you get some brushes, a drop cloth, and some rollers as well.
Painting can be a messy project, but the outcome can be dramatic. To make the project a little more fun, make sure you invite a friend or family member to help!

Record lap gives Hamilton 6th straight pole at Australian GP

MELBOURNE, Australia (AP) — Lewis Hamilton produced the fastest lap ever at the Australian Grand Prix to take pole position at the Formula One season opener for the sixth consecutive year.
The five-time world champion overhauled teammate Valtteri Bottas' leading time with seconds remaining to top qualifying Saturday in 1 minute, 20.486 seconds.
"Oh man. I'm shaking it was so close out there," Hamilton said in a post-session TV interview. "I'm so proud. Valtteri did an exceptional job out there, so close."
Bottas was second in 1:20.598 and will start alongside his Hamilton on the front of the grid in Sunday's Grand Prix. Two-time defending champion Sebastian Vettel was third and Red Bull's Max Versteppen split the Ferraris by finishing fourth in front of Charles Leclerc.
Hamilton collected the 84th pole position of his career and his eighth in Australia.
Asked about matching Michael Schumacher and Ayrton Senna's record for most pole positions at an F1 circuit, the British driver was slightly taken aback.
"I didn't even know about that," Hamilton said. "That's news to me."
He'll be focused more on the race, having only been able to convert one of his five most recent pole starts here into a victory — in 2015.
The Ferraris appeared to be the fastest cars in winter testing, but so far haven't been able to top the Mercedes in any of the three practice sessions or qualifying in Melbourne.
That doesn't bother Vettel, who has won here the last two years despite finishing behind Hamilton in qualifying.
Asked if Ferrari can make it three in a row in Australia, Vettel said: "Of course, I think we can. We have a good race car. We're in good form."
"Obviously Mercedes are clear favorites, but we're here to race."
Leclerc had the quickest time in the first of the three qualifying sections but slipped back to third and then fifth.
Both Renault drivers missed the last stage of qualifying with Nico Hulkenberg 11th after the second run and Daniel Ricciardo 12th in his first qualifying session for his new team.
Pierre Gasly ended his first qualifying run for Red Bull in the garage and was among the five drivers who failed to progress out of the first qualifying section.
He was joined by Williams drivers George Russell and Roberta Kubica, who slid off the track after puncturing a tire and had the slowest time of all 20 vehicles in his comeback to F1 following injuries he sustained in a serious rallying accident before the start of the 2011 season.

Prevention and Treatment Allergies and asthma are chronic conditions that affect up to 25 percent of Canadians; most of us are either affected ourselves or know someone who is.
Allergic conditions range from mild "hay fever" to life-threatening anaphylaxis, and asthma is one of the most frequent causes of hospitalization in children. A diagnosis of allergy, asthma or anaphylaxis can be a life-altering event for individuals and their families, and the costs associated with medical care and absences from work and school make this a significant public health issue.
It is not uncommon for people with allergies and asthma to feel isolated and anxious. Sometimes there is a sense that others do not understand the gravity of their condition. It can also be difficult for parents to trust that a child with allergies or asthma will be safe and act responsibly. Those affected may also worry about the potential for a severe asthma attack or allergic reaction, though even mild cases can disrupt lifestyle if not well-managed. In all cases, the importance of a positive outlook cannot be understated; this is especially true when dealing with children, who are quick to adopt a nervous parent's attitude.
While allergies and asthma cannot be cured, they can be effectively managed with proper education, preventive measures, and professional care.
The best way to reduce the risks associated with these conditions is one of Awareness, Avoidance and Action.
"While allergies and asthma cannot be cured, they can be effectively managed with proper education, preventive measures, and professional care."
Awareness starts with an accurate medical assessment, preferably by an allergist. This allows patients and their families to know exactly what prompts the reaction and to inform friends, teachers, and co-workers about the condition; having a letter from the physician on hand is helpful in this regard. While the patient and family may need some time to gain a thorough understanding of the implications of the diagnosis, it is vital to ensure that allergic or asthmatic children comprehend their condition well enough to be able to take responsibility for their own safety as soon as possible.
Avoidance involves preventing exposure to allergens. If the allergen is a food, adopting new eating habits and learning to read food labels carefully can present an initial challenge. If there is an allergy to airborne substances, exposure can be minimized by taking simple steps, like shutting windows on windy days. Avoidance may also encompass taking preventative medications before the allergy season begins, which can make symptoms easier to control, and possibly prevent them.
Action involves being prepared and knowing how to respond to worsening symptoms or an emergency. It is crucial for patients with severe allergies and asthma to carry both preventative and emergency medications, and that they be accessible at all times. It is best to develop an emergency action plan with a physician, and to share it with others; in particular, parents of children with life-threatening allergies should meet with the school before the year begins to establish a plan of action. Special attention may be needed when the usual routine is altered, such as camp, vacations, start or change of school or job, and parties.
The outlook for allergy and asthma patients is positive. Public awareness campaigns and informational websites have vastly improved the public's understanding of these conditions. Extensive medical research and pharmaceutical developments in recent years give hope for more effective treatment options. Though there is no such thing as a 100% risk-free lifestyle for people with asthma and allergies, most patients who seek appropriate medical care are able to enjoy a normal and productive life, with rare absences from school or work. The key is to manage risks and the associated anxiety by staying educated, informing others, and being prepared.
