* Appends the specified content at the index in the original string. * If a range *ending* with index is subsequently moved, the insert will be mov

* Does what you'd expect.

* Generates a sourcemap object with raw mappings in array form, rather than encoded as a string. * Useful if you need to manipulate the sourcemap f

* Removes the characters from `start` to `end` (of the original string, **not** the generated string). * Content appended or prepended at positions

* Same as `s.replace`, but replace all matched strings instead of just one.

* Adds the specified character index (with respect to the original string) to sourcemap mappings, if `hires` is false.

* Appends the specified content to the end of the string.
