You to verify what type was used. Of course you could only use the operator but using type guard saves information about the type of the variable which makes it unnecessary to check its type each time. List the main benefits of TypeScript. I think this question should be one of the first to be asked when discussing TypeScript because an extended answer to it may also include answers to other questions from this post.
The biggest advantage of TypeScript is of course types! Both built in types and the ability to create your own types and interfaces are useful. TypeScript offers a lot of typing possibilities which Phone Number List allows you to create much cleaner code than JavaScript. Types allow you to eliminate or reduce a significant percentage of errors that can be made in JavaScript and which the TypeScript compiler will not allow. The code in TS is much more predictable and easier to debug. Another advantage is the default implementation of experimental functions such as decorators and optional chaining.
In addition TypeScript offers access modifiers which have only recently been introduced in pure JavaScript. TypeScript also allows you to use JavaScript code which means you don't have to rewrite the entire codebase at once. This can be done gradually. Summary These dozen or so questions are far from enough to be well prepared for a recruitment interview. Once again I strongly encourage you to check other blog entries and download the e book Junior JavaScript Developer Recruitment Questions.
