string interpolation {{ }} code example

Example 1: string interpolation

/*In order to embed expressions within normal strings,
you would use the following syntax:*/
let a = 5;
let b = 10;
console.log('Fifteen is ' + (a + b) + ' and\nnot ' + (2 * a + b) + '.');
// "Fifteen is 15 and
// not 20."

/*Now, with template literals, you are able to make use of the syntactic sugar,
making substitutions like this more readable:*/
let a = 5;
let b = 10;
console.log(`Fifteen is ${a + b} and
not ${2 * a + b}.`);
// "Fifteen is 15 and
// not 20."

Example 2: string interpolation

const number = 42;
const message = `The number is ${number}`;

message; // => 'The number is 42'
