TypeScript String

Summary: in this tutorial, you’ll learn about the TypeScript string data type.

Like JavaScript, TypeScript uses double quotes (") or single quotes (') to surround string literals:

let firstName: string = 'John';
let title: string = "Web Developer";Code language: JavaScript (javascript)

TypeScript also supports template strings that use the backtick (`) to surround characters.

The template strings allow you to create multi-line strings and provide string interpolation features.

The following example shows how to create a multi-line string using the backtick (`):

let description = `This TypeScript string can 
span multiple 
lines
`;Code language: JavaScript (javascript)

String interpolations allow you to embed the variables into the string like this:

let firstName: string = `John`;
let title: string = `Web Developer`;
let profile: string = `I'm ${firstName}. 
I'm a ${title}`;

console.log(profile);Code language: JavaScript (javascript)

Output:

I'm John. 
I'm a Web Developer.Code language: PHP (php)

Summary

• In TypeScript, all strings get the string type.
• Like JavaScript, TypeScript uses double quotes ("), single quotes ('), and backtick (`) to surround string literals.
