String interpolation in JavaScript?

Consider this code:

var age = 3;

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

Are there any other ways to insert the value of a variable in to a string, apart from string concatenation?

Solution

  • Since ES6, you can use template literals:

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

    P.S. Note the use of backticks: ``.
