Discussion on: TypeScript is the Only Programming Language you Need to Learn. One language to rule them all!

Yep I totally agree with this. I use Ruby at work, Lua at home and JavaScript both at work and at home; and the types of errors I deal with are almost always related to much more complicated things than a value having the wrong type.

Having worked with languages like C and Pascal before, I'd even say it's the opposite: not having to type your variables is one less thing to keep in your head making a bit more room for the actual logic you're trying to translate into program code, so it helps with reducing bugs caused by dumb oversights.

Just as a small anecdote to underline this: The last bug I found today was that a function to calculate the length of some text was being called before the applications fonts had been fetched, so it used some default font of the browser instead and the result was off by a few pixels. No amount of typing could have fixed this, and in the end the problem was fixed by reasoning about what's happening. Those sorts of high-level problems are the ones I find myself solving most of the time, whereas type mismatches are usually a matter of reading an error message and saying "Oh, of course, this has to be a number"
