Template literals are string literals allowing embedded expressions. You can use multi-line strings and string interpolation features with them. They were called "template strings" in prior editions of the ES2015 specification.
Syntax
`string text`
`string text line 1
string text line 2`
`string text ${expression} string text`
tag `string text ${expression} string text`
Examples
console.log(`string text line 1
string text line 2`);
// "string text line 1
// string text line 2"
var a = 5;
var b = 10;
console.log(`Fifteen is ${a + b} and
not ${2 * a + b}.`);
// "Fifteen is 15 and
// not 20."
