Sprint.js

Sprint is a high-performance, 5KB (gzipped) DOM library for modern browsers. Sprint notably shines on bandwidth and resource constrained devices such as phones and tablets.

Sprint has a familiar, jQuery-like chainable API:

$("div").addClass("new").append("<p>Hi Sprint</p>");

Philosophy

Sprint is an alternative—not a replacement—for jQuery. jQuery offers more features, handles more edge cases and supports more browsers. Sprint is just a thin layer making the DOM friendlier without sacrificing on performance.

Performance

Sprint relies on newer APIs supported by modern browsers (read: IE10+) and optimizes a bunch of other things in order to provide you with fast DOM operations.

Here are a few performance tests of some popular methods (Chrome 42, OS X 10.10.3) :

.add()

→ View on jsperf

.attr()

→ View on jsperf

.css()

→ View on jsperf

.has()

→ View on jsperf

.map()

→ View on jsperf

.next()

→ View on jsperf

.not()

→ View on jsperf

.parents()

→ View on jsperf

.position()

→ View on jsperf

.slice()

→ View on jsperf

.text()

→ View on jsperf

Thanks to its reduced feature set, Sprint is also a lot faster to parse and execute (about 40 times faster than jQuery).
