javascript单引号

JavaScript allows you to use 3 types of quotes:

JavaScript允许您使用3种引号：

• single quotes
  单引号
• double quotes
  双引号
• backticks
  反引号

The first 2 are essentially the same:

前两个基本相同：

const test = 'test'const bike = "bike"

There’s little to no difference in using one or the other. The only difference lies in having to escape the quote character you use to delimit the string:

使用任何一个几乎没有差异。 唯一的区别在于必须转义用于定界字符串的引号字符：

const test = 'test'const test = 'te\'st'const test = 'te"st'const test = "te\"st"const test = "te'st"

There are various style guides that recommend always using one style vs the other.

有多种样式指南建议始终使用一种样式，而不是另一种样式。

I personally prefer single quotes all the time, and use double quotes only in HTML.

我个人更喜欢一直使用单引号，并且仅在HTML中使用双引号。

Backticks are a recent addition to JavaScript, since they were introduced with ES6 in 2015.

自2015年在ES6中引入反引号以来，反引号是JavaScript的最新成员。

They have a unique feature: they allow multiline strings.

它们具有独特的功能：它们允许多行字符串。

Multiline strings are also possible using regular strings, using escape characters:

多行字符串也可以使用常规字符串，并使用转义字符：

const multilineString = 'A string\non multiple lines'

Using backticks, you can avoid using an escape character:

使用反引号，可以避免使用转义符：

const multilineString = `A stringon multiple lines`

Not just that. You can interpolate variables using the ${} syntax:

不仅如此。 您可以使用${}语法插值变量：

const multilineString = `A stringon ${1+1} lines`

, that dives more into the nitty-gritty details.

将更深入地探讨细节。
