@ampproject/remapping intelligently remaps generated code positions to their original source. It excels at processing source maps, handling complex scenarios like chained or multi-level transformations. This utility empowers developers to debug efficiently by accurately linking errors and breakpoints back to the source code, offering a vital tool for projects using transpilers, minifiers, or other code generation processes. It’s a core component of AMP's build tools and a powerful asset for any modern web development workflow needing precise source mapping.
