It's a build tool, written in node, so it was the first front end build tool that saw wide usage 3-4 years ago. Used for things like concatenating and minifying your CSS and JS for production. It was succeeded by Gulp, which was succeeded by Browserify, which was succeeded by Webpack, and then I moved to the backend because fuck this shit.
