This makes it easier to use third-party dependencies in this tool (e.g. adding compression using algorithms not available in Python). It is also much faster - locally js2c.py takes ~1.5s to generate the output whereas this version takes ~0.1s - and consumes less memory (~110MB v.s. 66MB). This also modifies the js2c.py a bit to simplify the output, making it easier to compare with one generated by the C++ version. Locally the output from the two are identical. We'll remove js2c.py in a subsequent commit when the C++ version is used by default. PR-URL: https://github.com/nodejs/node/pull/46997 Reviewed-By: Yagiz Nizipli <yagiz@nizipli.com>
