jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2

<h2>Some things users love about Sublime Text</h2>
<div class="section odd">
<h3>Goto Anything</h3>
<p>Use Goto Anything to open files with only a few keystrokes, and instantly jump to symbols, lines or words.
</p><p>Triggered with <span class="pc key">Ctrl+P</span><span class="mac key">⌘P</span>, it is possible to:
</p><ul>
<li>Type part of a file name to open it.
</li><li>Type <code>@</code> to jump to symbols, <code>#</code> to search within the file, and <code>:</code> to go to a line number.
</li></ul>
<p>These shortcuts can be combined, so <code>tp@rf</code> may take you to a function <em>read_file</em> within a file <em>text_parser.py</em>. Similarly, <code>tp:100</code> would take you to line 100 of the same file.</p>
</div>
<div class="section even">
<h3>Multiple Selections</h3>
<p>Make ten changes at the same time, not one change ten times. Multiple selections allow you to interactively change many lines at once, rename variables with ease, and manipulate files faster than ever.
</p><p>Try pressing <span class="pc key">Ctrl+Shift+L</span><span class="mac key">⇧⌘L</span> to split the selection into lines and <span class="pc key">Ctrl+D</span><span class="mac key">⌘D</span> to select the next occurrence of the selected word. To make multiple selections with the mouse, take a look at the <a href="http://www.sublimetext.com/docs/2/column_selection.html">Column Selection</a> documentation.
</p></div>
<div class="section odd">
<h3>Command Palette</h3>
<p>The Command Palette holds infrequently used functionality, like sorting, changing the syntax and changing the indentation settings. With just a few keystrokes, you can search for what you want, without ever having to navigate through the menus or remember obscure key bindings.
</p><p>Show the Command Palette with <span class="pc key">Ctrl+Shift+P</span><span class="mac key">⌘⇧P</span>.
</p></div>
<div class="section even">
<h3>Distraction Free Mode</h3>
<p>When you need to focus, Distraction Free Mode is there to help you out. Distraction Free Mode is full screen, chrome free editing, with nothing but your text in the center of the screen. You can incrementally show elements of the UI, such as tabs and the find panel, as you need them.
</p><p>You can enter Distraction Free Mode using the <span class="menu">View/Enter Distraction Free Mode</span> menu.
</p></div>
<div class="section odd">
<h3>Split Editing</h3>
<p>Get the most out of your wide screen monitor with split editing support. Edit files side by side, or edit two locations in the one file. You can edit with as many rows and columns as you wish.
</p><p>Take advantage of multiple monitors by editing with multiple windows, and using multiple splits in each window.
</p><p>Take a look at the <span class="menu">View/Layout</span> menu for split editing options. To open multiple views into the one file, use the <span class="menu">File/New View into File</span> menu item.
</p></div>
<div class="section even">
<h3>Instant Project Switch</h3>
<p>Projects in Sublime Text capture the full contents of the workspace, including modified and unsaved files. You can switch between projects in a manner similar to Goto Anything, and the switch is instant, with no save prompts - all your modifications will be restored next time the project is opened.
</p></div>
<div class="section even">
<h3>Plugin API</h3>
<p>Sublime Text has a powerful, Python based plugin <a href="http://www.sublimetext.com/docs/2/api_reference.html">API</a>. Along with the API, it comes with a built in Python console to interactively experiment in real time.
</p></div>
<div class="section odd">
<h3>Customize Anything</h3>
<p>Key Bindings, Menus, Snippets, Macros, Completions and more - just about everything in Sublime Text is customizable with simple JSON files. This system gives you flexibility as settings can be specified on a per-file type and per-project basis.
</p></div>
<div class="section even">
<h3>Cross Platform</h3>
<p>Sublime Text is available for OS X, Windows and Linux. One license is all you need to use Sublime Text on every computer you own, no matter what operating system it uses.
</p><p>Sublime Text uses a custom UI toolkit, optimized for speed and beauty, while taking advantage of native functionality on each platform.
