TypeScript Comments


TypeScript Comments

In this tutorial, we will learn how to write comments in TypeScript language. We will go through the different types of comments and how to use them in a program.


What are Comments

Comments are non-executable statements that are used to explain and document the code. They help improve the readability of the code and make it easier for others to understand. Comments can also be used to temporarily disable code during testing and debugging.


Syntax

The syntax to define comments in TypeScript is:

// Single line comment
/* Multi-line comment
   continues here */


Single line comments

  1. Single line comments in TypeScript start with // and continue to the end of the line.
  2. They are used to add short explanations or notes within the code.

TypeScript Program

console.log("Hello, World!");  // Print Hello, World! to the console

Output

Hello, World!


Multiline comments

  1. Multiline comments in TypeScript start with /* and end with */.
  2. They can span multiple lines and are used for longer explanations or to comment out blocks of code.

TypeScript Program

/* Print Hello, World! to the console
   This is a multi-line comment */
console.log("Hello, World!");

Output

Hello, World!
