在除IE之外的其他浏览器上工作的模板文字 [英] Template literals working on other browser except IE
问题描述
我正在使用javascript并使用模板文字，它正在使用Chrome和Firefox，但它无法在Internet Explorer（IE）上运行。
I am working on javascript and using "Template literals", which is working on the Chrome and Firefox, but it is not working on the Internet Explorer(IE).
var a = 10;
console.log(`${a}`)
推荐答案
模板文字是ES6，IE支持很少 ES6功能。它不支持模板文字。
Template literals are ES6, and IE supports very few ES6 features. It doesn't support template literals.
对于你正在做的事情，只需执行 console.log（a）代替：
For what you're doing, simply do console.log(a) instead:
var a = 10;
console.log(a)
但如果您的真实代码比这更复杂，那么你将会要么必须手动连接，例如：
But if your real code is more complicated than that, you'll either have to concatenate manually, eg:
`foo${somevar}bar${somevar2}baz`
更改为
'foo' + somevar + 'bar' + somevar2 + 'baz'
或者，更好的选择，如果您喜欢模板文字的语法并且不喜欢纯字符串连接，那么将Babel集成到您的构建过程中以将ES6 +语法（包括模板文字）自动转换为ES5 ：
Or, a better option, if you like the syntax of template literals and don't like plain string concatenation, would be to integrate Babel into your build process to transpile ES6+ syntax (including template literals) to ES5 automatically:
（Babel将不仅是转换模板文字，它还会将新的语法所有转换为ES5，如解构，箭头函数， async / await 等 - 对于更大的代码库，它非常重要，允许程序员使用最新最好的语言版本，同时保持与IE等古老浏览器兼容）
(Babel will not only transpile template literals, it'll transpile pretty much all of the newer syntax to ES5, like destructuring, arrow functions, async/await, etc - for larger codebases, it's pretty much essential, allowing the programmers to write in the latest and greatest version of the language while remaining compatible with ancient browsers like IE)
