Some JavaScript engines and Babel have disabled the tail call optimization because of its complexity.

@MichalZalecki as you can see on compatibility table, still in 2017 almost no major js engine supports TCO. I am not sure why is that... probably full compliance with spec is waaaay harder than what this plugin tries to achieve.
@xtuc is right. Babel used to have TCO (i guess in version 5.x) but it was quite buggy. I found some old issues and tried to create workarounds for them (mostly for function scope). My workaround was simply not to attempt to optimize it at all :D
