我如何包含所有js文件，就像我们将所有css文件添加到一个main.css中一样

Question

We can use all css files as one file for example main.css:

@import url(bootstrap.css);
@import url(bootstrap.min.css);
@import url(bootstrap-theme.css);
@import url(bootstrap-theme.min.css);
@import url(style.css);
@import url(w3.css);

How can we include and use all js files as one main.js and use all javascript files for example

main.js

<script src="http://127.0.0.1:7070/js/aa.js">
<script src="http://127.0.0.1:7070/js/bb.js">
<script src="http://127.0.0.1:7070/js/cc.js">
<script src="http://127.0.0.1:7070/js/dd.js">
<script src="http://127.0.0.1:7070/js/ee.js">

Answer 1

You can't natively include JS files like the import statement in CSS (though it's important to note that the CSS import still downloads multiple files, it's just a convenience for organizing the rules. )

Have a look at tools like Webpack, require.js, Grunt, and Gulp. All of which do concatenation and minification for you as build steps.
