However there are also some improvements such as with `.ajax()`, `.append()`, etc. It's all detailed here: a.button.icon-doc(href="documentation" target="_blank") Documentation div pre code.language-javascript. // Simple events like jquery u("button").on('click', function(){ alert("Hello world"); }); // Send form through ajax when submitted u('form.login').ajax(function(err, res){ window.href = '/user/' + res.id; }); section.flex.two div :markdown ## Tiny and Clear **3kb** when gzipped means it will load in a snap on mobile. The core is reusable so new features are also tiny. You can see two features of Umbrella JS source code on the right, or check it all on github: a.button.icon-g(href="https://github.com/franciscop/umbrella" target="_blank") Source on Github div pre code.language-javascript. // Find the nodes matched by a selector u.prototype.find = function(selector) { return this.map(function(node){ return u(selector || "*", node); }); }; // Check if any node matches the selector u.prototype.is = function(selector){ return this.filter(selector).length > 0; }; section.flex.two div :markdown ## Tested and Performant The speed is similar to jquery and there are many tests, including performance ones. They run on development, on deploy and live in different browsers so you know everything will work as expected. div pre code.language-javascript. it("can select by class", function() { expect(u('.demo').length).to.equal(1); }); it("can select li inside ul", function() { var ul = base.find('li').closest('ul'); expect(ul.length).to.equal(1); }); section.flex.two div :markdown ## MIT License If you love something set it free.
