Loops through all the min-width breakpoints and stores them in an array.
Creates a custom event called switch, which gets fired when the breakpoint has changed.
The custom event provides the name of the breakpoint and width in pixels.
Each breakpoint name is in the following format: bp-{number}.
See it in action + some notes! 😀
Example
Using the custom event.
ML.El.evt(window, 'switch', function(e) {
console.log(e.detail.name); // name of the breakpoint
console.log(e.detail.size); // width in px of breakpoint.
});
