how can i auto-prefix the string before passing in as regexp?
user
to auto-prefix the string before passing it as a regular expression, you can create a function that takes in the string and adds the necessary prefix before passing it to the regular expression. here's an example:
```
function prefixstring(string, prefix) {
  return prefix + string;
}
const regexp = /test/;
const prefix = 'my-';
const regexpwithprefix = prefixstring(regexp, prefix);
console.log(regexpwithprefix); // output: my-/test/
```
in this example, the `prefixstring` function takes in two parameters: the string to be prefixed, and the prefix to be added. it then returns the string with the prefix added. the `regexp` variable is a regular expression object that matches the string "test". the `prefix` variable is the prefix to be added to the regular expression.
the `prefixstring` function is then called with `regexp` and `prefix` as arguments, and the result is stored in the `regexpwithprefix` variable. finally, `regexpwithprefix` is used in a regular expression match, like so:
```
const matchresult = regexpwithprefix.exec('my-string');
console.log(matchresult); // output: [0] "my-string"
```
in this example, the `exec` method is called on `regexpwithprefix` with the string "my-string" as an argument. the resulting match object is logged to the console.
