Poor JavaScript.

JS is awesome once you understand it very well

If people put the same effort they do in c# or java into learning JS they wont be complaining a lot

JS has it's shortcoming but again what language doesn't, there isn't something as all you need is one language. One just need to know pros and cons of each one of them.

As Engineers, it's up to us to master our craft expend our toolbelt and use the right tool for the job

Most dev get wiser with time and they stop being a one languge fanboy

I like Javascript... :)
And PHP...
