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?

Since ES6, you can use template literals:



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



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