Key Concepts in TypeScript
There are three things that make Typescript so useful:
- Classes and OOP
- boosting your confidence
- catching errors before they reach production
- making it possible to refactor code
- saving you time from writing tests
- giving you a good coding experience
When working with new codebases and in larger teams, TypeScript will give you more confidence. You will be less concerned if you are familiar with TypeScript and join a new team or project that uses it. You can count on TypeScript to help you out. Because you can look at something and quickly infer how it works, the language improves code readability and predictability. The type system is to blame for this.
Because TypeScript will detect errors for you, refactoring code becomes easy. When you rename a function, it will warn you if you fail to use the new name someplace else. TypeScript will correct you if you change the form of an interface or type and eliminate a property that you thought wasn't being utilised.
In essence, TypeScript is a JS linter. Alternatively, JS with compiler-friendly documentation.
Nevertheless, even if you don't use TypeScript to its full potential, it's a useful tool to have in your toolbox. It's simple to start small and gradually expand your capabilities, learning and adding new features as you go. There's no need to be terrified of TypeScript because it's practical and accommodating to beginners.
