This article mainly introduces how regular expressions match comments in JavaScript code. The code is given directly below. Friends who need it can refer to it. I hope it can help everyone.

Sometimes we need to remove js comments to reduce redundancy in the code. Sometimes too many comments lead to a large page size.

The comment icon is as follows:

1. Match multi-line comment regular expression:


/(?:^|\n|\r)\s*\/\*[\s\S]*?\*\/\s*(?:\r|\n|$)/g
Copy after login

2. Single-line comment regular expression:


/(?:^|\n|\r)\s*\/\/.*(?:\r|\n|$)/g
Copy after login
