IndexedDB
Mozilla
IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files/blobs. This API uses indexes to enable high-performance searches of this data. While web storage is useful for storing smaller amounts of data, it is less useful for storing larger amounts of structured data. IndexedDB provides a solution. IndexedDB is a transactional database system, like an SQL-based Relational Database Management System (RDBMS). However, unlike SQL-based RDBMSes, which use fixed-column tables, IndexedDB is a JavaScript-based object-oriented database. IndexedDB lets you store and retrieve objects that are indexed with a key; any objects supported by the structured clone algorithm can be stored. You need to specify the database schema, open a connection to your database, and then retrieve and update data within a series of transactions. Like most web storage solutions, IndexedDB follows the same-origin policy.Starting Price: Free -

Three.js
Three.js
Three.js is a JavaScript 3D library. The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available in the examples. To actually be able to display anything with three.js, we need three things, scene, camera, and renderer, so that we can render the scene with the camera. In addition to the WebGLRenderer, Three.js comes with a few others, often used as fallbacks for users with older browsers or for those who don't have WebGL support for some reason. Create a loop that causes the renderer to draw the scene every time the screen is refreshed (on a typical screen this means 60 times per second). Anything you want to move or change while the app is running has to go through the animate loop. You can of course call other functions from there.Starting Price: Free -

Maqetta
Maqetta
Maqetta is an open source project that provides WYSIWYG visual authoring of HTML5 user interfaces. The Maqetta application itself is authored in HTML, and therefore runs in the browser without requiring additional plugins or downloads. Maqetta is available under a commercial-friendly open source license. You can download the source code and install it on your own server, customize the code to fit your needs and/or contribute improvements to the open source project. The HTML pages created by Maqetta typically work across all popular browsers, including IE (caveat: this depends on the JavaScript toolkit you use and coding details). But if you want to run the Maqetta application, you'll need to use a recent release of one of the following browsers, all of which support the HTML5 features that Maqetta requires. The project's code is built using 100% open standards technologies. -

CoffeeScript
CoffeeScript
Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.Starting Price: Free -

JsPHP
JsPHP
The free open-source JsPHP library. The JsPHP website is a 100% free community resource that provides a collaborative platform and web-based Integrated Development Environment (IDE) for building an open-source JavaScript library called JsPHP that provides an implementation of the PHP API for JavaScript environments. An Integrated Development Environment (IDE) is a tool for writing computer programs, and that's what the JsPHP website is a tool for creating and testing software. In the JsPHP IDE registered users can edit the JavaScript functions in the JsPHP library and can also write code to test that those functions are working properly or to test how well those functions perform (how fast they run when they are executed on the computer). If you're just starting out with learning JavaScript then helping out at JsPHP is the perfect way for you to get started because we have lots of beginner-level work that needs to be done that you could help us with.Starting Price: Free
