Use Template Literals for String Interpolation in JavaScript

Template literals, introduced in ECMAScript 6 (ES6), provide a more concise and readable way to interpolate variables and expressions within strings compared to traditional string concatenation.

Take a look at the example below. Template literals are enclosed in backticks (` ) instead of single or double quotes. You can include placeholders ${expression} within the string, and JavaScript will automatically evaluate the expression and substitute it with its value.

Benefits of using template literals:

  • Improved readability: Interpolating variables within the string directly enhances code readability.
  • Multi-line strings: Template literals support multi-line strings without needing manual line breaks.
  • Complex expressions: You can include complex JavaScript expressions within placeholders.

Template literals make your code more elegant and easier to maintain than traditional string concatenation methods. Remember that template literals are supported in modern browsers and environments that support ES6 and later versions of JavaScript.

const name = 'Bob';
const age = 30;

const greeting = `Hello, my name is ${name} and I am ${age} years old.`;
console.log(greeting);
