Features

• Universal interface for multiple data types: arrays, typed arrays, tables, Map, Set, generators and @@iterator protocol;
• The rich set of iterators;
• Built-in self JIT compilation of requests provides a very high speed of execution, which is comparable to the native cycles JavaScript;
• Support lightweight threads based on generators;
• Work in browsers, as well as on the server (node.js);
• The engine is written in pure JavaScript and does not have any dependencies;
• The source code is designed to work with Google Closure Compiler in advanced mode;
• The modular architecture allows to build your library;
• Good code coverage;
• Detailed documentation with examples.

Usage

// Iterate over the elements in reverse order starting with the 5th
$C(document.querySelectorAll('.foo')).forEach((el) => {
  ...
}, {
  reverse: true,
  startIndex: 5
});

// Return an array of all the even elements of the original array
$C([1, 2, 3, 4]).get((el) => el % 2 === 0);

// Create a new object based on the source,
// {a: 2, b: 4}
$C({a: 4, b: 16}).map(Math.sqrt);

// Iterate very large object in the lightweight thread
await $C(new Array(1e8)).thread().forEach(() => {
  ...
});
