#2 - Type, Type Inference, Type Annotations in TypeScript
Показать описание
In this video, I have explained what is Type, Type Inference, Type Annotations in TypeScript.
Type Inference:
TypeScript has a feature called type inference, which allows the compiler to automatically determine the types of variables if you don't explicitly specify them.
For example, if you declare a variable and assign it a numeric value, TypeScript will infer its type as number without needing explicit type annotations.
Type inference helps reduce verbosity in your code while still providing type safety.
example:
let age = 30;
5. Type Annotations:
Type annotations in TypeScript involve explicitly specifying the types of variables, function parameters, and return values.
let age: number = 30;
let name: string = "John";
let isStudent: boolean = true;
