How Does JavaScript String Interpolation Work Using Template Literals?

String Interpolation in JavaScript

String interpolation allows for the insertion of variables and expressions into strings. One common method is string concatenation, as seen in the code below:

var age = 3;

console.log("I'm " + age + " years old!");

However, since the introduction of ES6, an alternative approach has emerged: template literals. Template literals are enclosed in backticks (``) and allow for the seamless insertion of variables and expressions using the ${} syntax.

const age = 3
console.log(`I'm ${age} years old!`)

This syntax offers a more concise and readable way to interpolate variables into strings. The interpolated value can be any valid JavaScript expression, making it a powerful tool for creating dynamic and interactive content.
