One of the big wins of arrow functions is eliminating the this ambiguity. ![]() The 'swap this and that' pattern in JS always struck me as a hack. When I'm reviewing code and have to stop and figure out what this is referring to, it makes me frown with arrow functions I always know exactly what this is.
