Q & A

JavaScript lacks types and static checks, and it's more likely to introduce errors at runtime, not only because they cannot exist with TypeScript but because they are not prevented by any tool or mechanism. TypeScript provides some basic guarantees about the validity of the parameters or variables you use.

This is because class diagrams are useful for representing the static structure of a system and the associations between them.

As we mentioned previously, TypeScript comes with its own refactoring tool, namely the server executable, which integrates well with VSCode. Because the server scans the program and resolves all the types of the variables or objects, it can provide additional operations such as refactoring. This would be more difficult or limited when using JavaScript as there are no types to check against.

I would explain to them the difference between JavaScript and TypeScript and how easy it is to convert existing projects into TypeScript, piece by piece. I would also relay the benefits of type checking, refactoring, and having a better coding experience. I would conclude that TypeScript is widely used and documented, so there should be no fear in adopting it in practical projects.

TypeScript comes with its own refactoring tool, namely the server executable. This tool offers code inspection facilities that VSCode uses natively.

We use external libraries to avoid implementing hard-to-understand concepts that require some expertise. For example, with Immutable.js, writing a similar library that works with immutable data is a daunting feat. We must carefully avoid all sorts of issues, such as memory leaks, performance degradation, and bad API implementation. In many cases, it's also counterproductive as you won't have enough time to materialize business goals as you will lose time and money working on irrelevant features.
