### [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
