Introduction to TypeScript Programming
- Type Checking: TypeScript provides type checking, which can help catch errors early in the development process. This saves time and makes it easier to debug code.
- Classes and Interfaces: TypeScript supports classes and interfaces, which makes it easier to organize code into reusable components.
- Modules: TypeScript has a module system that makes it easier to manage dependencies between code components.
Getting Started with TypeScript
To get started with TypeScript, you will need to install the TypeScript compiler and set up your development environment. Here are the steps to follow:
- Install Node.js and npm.
- Install TypeScript by running
npm install -g typescript.
- Create a new TypeScript file with a
- Compile the TypeScript file by running
TypeScript has several built-in types, including:
number: for numbers, such as integers and floating-point numbers.
string: for strings of text.
boolean: for values that are either
any: for values that can be of any type.
void: for values that do not return anything.
You can also define your own custom types using interfaces or classes.
Interfaces define a contract that an object must conform to. Here is an example of an interface:
In this example, the
User interface defines a contract for an object that must have a
name and an
Classes are a way to organize code into reusable components. Here is an example of a class:
