Include console..log statements only conditionally and remove them from production distribution of javascript file

I've got console.log statements all over the place in my JavaScript source files printing stuff out to the console that I don't want the user to see.

One way is to scan through all my JavaScript source files and remove the console.log statements.

But I was wondering if there was a way to have them in there but not execute them for production distributions. Is there a way to conditionally include them (or whatever you want) akin to C/C++/C# debug symbols?

#if DEBUG
  console.log("User IP Address: " + localStorage.getItem("userIP"));
#endif

I understand there's no way to distinguish between a production distro and a development one, and there are no binary symbols since there's no compilation of JavaScript to object files, but if the language were to include a special construct like #if <SYMBOL> with some pre-defined symbols, that would make life easier?

if you npm then you can use babel-plugin-transform-remove-console https://babeljs.io/docs/en/babel-plugin-transform-remove-console – tvankith Jan 26 '19 at 05:18

@tvankith Presently in the middle of debugging. Will come back in a day or so and tell you what I did. – Water Cooler v2 Jan 26 '19 at 07:35
