### [acornStripComments](index.js#L42)
> Strip all code comments, but not these that are marked as "ignored" like (`//!` and `/*!`).  
> Pass `opts.preserve: false` to remove even them.

**Params**

* `<input>` **{String}**: string from which to get comments    
* `[opts]` **{Object}**: optional options, passed to `acorn-extract-comments` and `acorn`  
  - `ast` **{Boolean}**: if `true` the ast is added to the resulting array
  - `line` **{Boolean}**: if `false` get only block comments, default `true`
  - `block` **{Boolean}**: if `false` get line comments, default `true`
  - `ignore` **{Function}**: check function, default check comment starts with `!`
  - `preserve` **{Boolean}**: if `true` keep comments that are ignored (that pass the `opts.ignore` check)
  - `locations` **{Boolean}**: if `true` result will include `acorn/esprima` format comment location object
  - `ecmaVersion` **{Number}**: defaults to `6`, acorn parsing version
* `returns` **{String}**: modified string  

**Example**

const fs = require('fs')
