ES6 Template Literals, the Handlebars killer?
I had a recent discussion with one of the awesome developers at the FT - @bjfletcher. We were looking at how viable it would be to replace a templating language, like Handlebars with ES6 Template Literals, in some manner.

Change width of element without reflow
I have a music player with an animated bar that displays the current position in the song. It is rendered with requestAnimationFrame and works by changing the width style of the div to X%, where X is the percentage of time through the current song.
