Template literals are a new feature introduced in ECMAScript 2015/ ES6. It provides an easy way to create multiline strings and perform string interpolation. Template literals are the string literals and allow embedded expressions.

Before ES6, template literals were called as template strings. Unlike quotes in strings, template literals are enclosed by the backtick (` `) character (key below the ESC key in QWERTY keyboard). Template literals can contain placeholders, which are indicated by the dollar sign and curly braces ($(expression}). Inside the backticks, if we want to use an expression, then we can place that expression in the ($(expression}).
