f string in javascript

In Javascript, we can use template literals to achieve string interpolation, similar to f-strings in Python. Template literals allow us to embed expressions and variables within a string literal by wrapping it with backticks (``). Here's an example:


index.tsx
const name = 'Alice';
const age = 27;

// Using template literals to perform string interpolation
const greeting = `Hello, my name is ${name} and I am ${age} years old.`;

console.log(greeting); // Output: Hello, my name is Alice and I am 27 years old.

8 lines

In the example above, we use ${} to embed variables within the string literal. This can be used with expressions as well:


index.tsx
const a = 10;
const b = 5;

// Using expressions in template literals
const result = `The result of ${a} + ${b} is ${a + b}.`;

console.log(result); // Output: The result of 10 + 5 is 15.
188 chars
8 lines

Template literals offer a convenient way to perform string interpolation in Javascript.
