Browsers that implement the WebCrypto API can be used to conduct a truly zero-trust, secure lottery in less than 200 lines of modern JavaScript code.

WebRTC can be used to build a plugin-free video conference with screensharing in pure JavaScript. Observables — proposed for ES7 — let application logic be expressed in a clean, functional and composable way.

There is one abstraction that can be used to implement such apparently diverse concepts as exceptions, generators, coroutines and even the backtracking mechanism present in Prolog.

JavaScript’s dynamic nature, first-class functions and prototypes could always be used for elegant metaprogramming. Proxies let programmers further blur the line between the native, user defined objects and the host objects.

Exploring Bitcoin can yield interesting surprises. The block chain already contains various gems hidden inside transactions — tributes, illegal data, even pictures and a patch fixing bug in a Bitcoin client.

Bitcoin is designed to support a wide variety of transaction types. Although currently the majority of transactions are standard payments to address it is possible to build more complex protocols.

AMD simplifies modularizing JavaScript applications but as it is not a browser built-in mechanism a loader library is still needed to bootstrap the process. Fortunately it is possible to write a loader that supports plugins in less than 850 characters of optimized code.

JavaScript widgets are traditionally built using <div> soup and a mixture of framework-specific scripts. Web Components aim to change the status quo by introducing standard way of building elements.

Monte Carlo is a method to solving problems that uses random inputs to examine the domain. Pi approximation is a simple example that illustrates an idea of how the Monte Carlo method works.

Generators and backtracking can be used to build a simple Prolog interpreter in less than 160 lines of JavaScript. It will tell us facts about the Forrester family and even solve the Einstein’s puzzle.

Two-way data binding greatly simplifies writing views in web applications. The code in this article uses Object.observe to implement a simple two-way data binding in about 100 lines of code.

Monad is a design pattern used to describe computations as a series of steps. They are extensively used in pure functional programming languages to manage side effects but can also be used in multiparadigm languages to control complexity.

Solving sudoku using the backtracking algorithm. Uses ES6 generators to create a stream of possible solutions.

Object properties were traditionally left unprotected in JavaScript or hidden, captured in a closure. Symbols and WeakMaps provide another alternative.

Generators can be used to represent infinite streams of values. The algorithm used below is the Sieve of Eratosthenes. for-of loops are used to iterate over values returned from the generator.

Promises and generators can be used together to describe complex asynchronous flow in a simple, synchronous way.
