JavaScript f string equivalent

  • by

The JavaScript equivalent of f-strings in Python or string interpolation in other programming languages is template literals. Template literals allow for string interpolation and are enclosed in backticks ( ) instead of single or double quotes. The ${} syntax is used to embed variables within the string literal.

To embed variables within a template literal, you can use the ${} syntax

const name = 'John';
const age = 30;
const message = `My name is ${name} and I'm ${age} years old.`;

The variables name and age are embedded within the string using ${}.

JavaScript f string equivalent example

Simple example code of using template literals in JavaScript:

Using template literals with conditional statements:

The conditional operator ?: is used within the template literal to determine which number is greater.

<!DOCTYPE html>
    const x = 10;
    const y = 20;
    const result = `The ${x > y ? 'greater' : 'less'} number is ${x > y ? x : y}.`;



JavaScript f string equivalent

Using template literals with object properties:

const person = {
  name: 'John',
  age: 30
const message = `My name is ${} and I'm ${person.age} years old.`;

Using template literals with function calls:

function greet(name) {
  return `Hello, ${name}!`;
const message = greet('John');
