console.profile()
Chrome dev tools tip of the day: use console.profile() and a timeout to gather stats at particular points in your code. For example, a hamburger menu opening.
onClick: function() {
console.profile('Hamburger Open');
setTimeout(function() {
console.profileEnd('Hamburger Open');
}, 1000);
// Do some stuff
}
This will create an entry in the profiles pane of the dev tools when the code executes.
