Solved: how to install typescript on ubuntu

In today’s programming world, TypeScript, a statically compiled language to write clear and simple JavaScript code, has gained much popularity. It offers the features of the modern day JavaScript that includes classes, interfaces, and static types. All this makes TypeScript a crucial element for developers. In this guide, we delve into how to install TypeScript on Ubuntu and understand some primary functions that will help you get started with the language.

Installing TypeScript on Ubuntu

Prior to installing TypeScript, make sure that you have Node.js and npm (Node Package Manager) installed on your Ubuntu system.

Installation steps are as follows:

1. Open your terminal.

2. Install Node.js and npm with the following command:

sudo apt update
sudo apt install nodejs npm

3. Once installed, verify the installation with command:

nodejs -v
npm -v

4. Now you’re ready to install TypeScript using npm. Run the following command:

sudo npm install -g typescript

5. After the installation, you can verify it by checking the version of TypeScript:

tsc -v

Understanding TypeScript Code

TypeScript is efficient for developing large scale applications. It’s one of the most loved and used languages among JavaScript developers. Here’s a simple program to get you started:

var message: string = "Hello World"

In this TypeScript code, the variable ‘message’ is declared with the type ‘string’. Later, the content of the variable ‘message’ is printed in the console using console.log() function.

Common TypeScript Libraries and Functions

TypeScript offers a number of libraries and functions that simplify the coding experience. Here are some popular libraries that TypeScript developers commonly use:

  • TypeScript Node: It is a library for working with TypeScript in Node.js.
  • TypeScript-React-Starter: A starter template for TypeScript and React with a detailed README describing how to use the two together.

Several built-in functions are also available in TypeScript, like every() function to test whether all elements in the array pass the provided function, filter() function to create a new array with all elements that pass the test implemented by the provided function, among others.

We hope this guide helps you in setting up TypeScript on Ubuntu system successfully and high-level understanding of its coding syntax. It definitely enhances your JavaScript coding experience by offering a variety of useful features and tools.
