Biggest "oh my god we're idiots" moment was when me and a colleague (both several years of professional experience at that point) spent almost a full hour debugging, diving into the internals of our frameworks and libraries, trying to figure out why our Typescript class just wouldn't initialise correctly.
Only to realise that we had written "contructor" instead of "constructor"
I still do this sometimes. It just goes to show how helpful syntax highlighting / static code analysis / type-checking tools can be. Working in dynamic languages is so much more messy and difficult because of this.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
