What is a template string?

Template strings are a new way to create strings in JS. We can serialize the template by using backquotes.

/ / ES5 Versionvar greet ='Hi I\ m Mark';//ES6 Versionlet greet = `Hi I\'m Mark`

In ES5, we need to use some escape characters to achieve the effect of multiple lines, but we don't need to be so troublesome in template strings:

/ / ES5 Versionvar lastWords ='\ n' +'I\ n' +'Am\ n' + 'Iron Man\ nAccording to the Bash ES6 Versionlet lastWords = `I Am Iron Man`

In the ES5 version, we need to add\ nto add a new line in the string. We don't need to do this in the template string.

/ / ES5 Versionfunction greet (name) {return 'Hello' + name +'!;} / / ES6 Versionfunction greet (name) {return `Hello ${name}! `;}

In the ES5 version, if you need to add an expression or value to a string, you need to use the + operator. In the template string s, we can embed an expression using ${expr}, which makes it cleaner than the ES5 version.
