> Go delivered most of the performance benefit at a fraction of the engineering cost. The biggest JS/TS shop on earth picked a harder, faster language for its flagship tool, and they did it because the effort calculus changed under them.

JS got popular for nontechnical reasons and TS is an attempt to make lemonade out of it.
