I&#x27;ve worked with both C# and JS for a number of years and to sum up why static typing is ultimately better than dynamic typing, is because of the type system which gives you compile time errors.<p>As programmers on the computer all day, the more work the computer does for us the better. With a type system the computer knows what the system is capable of, and so knows what you are doing - this means it can tell us precisely what members are available in &#x27;foo&#x27; when you type &#x27;foo.&#x27;, and it can accurately tell us that &#x27;bar&#x27; does not exist in foo when you type &#x27;foo.bar&#x27;.<p>With systems of even minor complexity this is a godsend when you don&#x27;t have to even read the documentation of a new API you want to use - you just use the autocomplete and contextual documentation to figure things out. It makes code fun again.<p>With dynamic typing, and especially with JS, the computer is mostly oblivious to what can&#x2F;cannot be done and you end up having to ctrl+F on method names, mispell something and it just gets added as another variable to the type, you can&#x27;t refactor variable names easily etc. It&#x27;s pretty bad in comparison.<p>Static typing isn&#x27;t all perfect though - sometimes types do get in the way where I wish more dynamic features would have been available. But at least now if C# etc can be used for webdev, then solving these problems will become something people will invest time in and we will finally see new innovation again - instead of yet-another-javascript library&#x2F;hack.
