How do you use the 'this' parameter in TypeScript?

Description : 'this' parameter provides type information for instance methods.

Answer :

The 'this' parameter in TypeScript provides type information for instance methods, allowing you to define the type of 'this' within a method. For example, 'class Counter { private count: number = 0; increment(this: Counter): void { this.count++; } }' specifies that 'this' inside 'increment' is of type 'Counter'. This ensures that the method is called with the correct context and improves type safety when dealing with instance methods.

TypeScript is a statically typed language that builds on JavaScript by adding optional types. It allows developers to catch errors at compile time rather than runtime, which can help improve code quality and readability. TypeScript code is transpiled to JavaScript, making it compatible with existing JavaScript codebases and environments.
