The Chrome Developer Tools Timeline shows "(anonymous function)" for all of the code that's running slow and so I can't figure out what's going on. Is there a trick to getting these named? It also won't allow me to jump to the source of these anonymous functions. I'm using ES6 w/ arrow functions and babel.
Don't use lambda functions in your code. Instead of:
async(function(){});
write:
function withName(){};
async(withName);
