Sorin Davidoi fd9d2baa6d Bug 1588637 - perf: Reduce memory allocation, avoid regular expressions and layout trashing r=davidwalsh 
Apply the following optimizations:
 - Don't use regular expressions where they can be avoided
 - Reduce unnecessary memory allocations (e.g. avoid doing a map and a filter by writing the code in an imperative fashion)
 - Reduce layout trashing by using `rAF` and `setTimeout`
 - Perform cheaper checks first in conditional statements

See commit messages for more details.

Source Maps

This package contains DevTools utilities for working with source maps.

This is used in multiple contexts:

  • The debugger loads this package directly when running from the launchpad in a tab by itself
  • The toolbox inside Firefox loads this package and passes it down to interested tools so that they can share a common instance of the utilities

Application Requirements

This package assumes that an application using this code will make the worker.js, and dwarf_to_json.wasm files available and call startSourceMapWorker(workerURL, wasmRoot) to initialize the worker and specify the location of the wasm asset.
