JavaScript Template Literals

String Interpolation:

• Template literals allow embedding expressions within strings using ${} syntax.
• Provides a more readable and concise alternative to string concatenation.

Multi-line Strings:

• Template literals support multi-line strings without the need for escape characters like \n.

Expression Evaluation:

• Expressions inside ${} are evaluated, allowing dynamic content insertion.

Example: Basic Usage

const name = 'John';
const message = `Hello, ${name}!`;

Example: Multi-line Strings

const multiline = `This is a
multi-line
string.`;

Example: Expression Evaluation

const a = 10;
const b = 20;
const sum = `The sum of ${a} and ${b} is ${a + b}.`;

 

Key Points

• Template literals provide a flexible way to create strings with embedded expressions.
• They enhance code readability and maintainability, especially for dynamic string generation.
• Template literals are widely used in modern JavaScript development for string interpolation and multi-line string creation.
