A new type of string literal syntax introduced in ES6 - template string. Technically explained, a template string is a string literal that embeds expressions within a string literal. To put it simply, it is a string with added variable function.

ES6 provides us with template strings, and the syntax uses backticks`. Template strings have the following three advantages:

Multi-line text
Inserting variables into the string
Insert expressions into strings

Basic syntax

The declaration of template strings is the same as that of ES5 strings.

// ES5
var name = 'xixi';
console.log(name);// xixi

// ES6
let name4ES6 = `一步`;
console.log(name4ES6);// 一步

Copy after login

Multi-line text

In the era when Jquery was popular, we often spliced html fragments and then replaced nodes. Write a piece of ES5 code for everyone to experience:

var str = '<html>'
+ '<p>啦拉拉</p>'
+ '<p>xixixi</p>'
+ '</html>';
console.log(str);// <html><p>啦拉拉</p><p>xixixi</p></html>

Copy after login

ES6 supports multi-line text, and the above code is much easier to implement.

let str4ES6 = `<html>
 <p>啦拉拉</p>
 <p>xixixix</p>
</html>`;

console.log(str4ES6);

Copy after login

You can insert variables or expressions

// ES5
var name = 'xixi';
var age = 27;
var info = 'my name is ' + name + ' , age is ' + age + '.';
console.log(info);// my name is xixi , age is 27.

Copy after login

ES6’s template string is much easier to implement. The key syntax is ${}, in which any js expression can be inserted.

let name = 'xixi';
let age = 27;

let info = `my name is ${name}, my age is ${age}. just a test ${1 + 10}!`;
console.log(info);// my name is xixi, my age is 27. just a test 11!

Copy after login
