Debugging transpiled javascript-- how does that work? -

-

there lots of ways transpile other variants (typescript, coffeescript, es6-->es5) 'common', es5 javascript. resulting script unreadable humans , impossible debug in browser as-is.

my understanding source maps aid in process, i'm not sure how thing. @ high level, how work, debugging transpiled javascript in ie/firefox/chrome? follow similar convention or have own way(s) of handling mapping?
