superstruct - A simple and composable way to validate data in Javascript.

---

A simple and composable way to validate data in JavaScript. Superstruct makes it easy to define interfaces and then validate JavaScript data against them. Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API.

streamjs - Lazy Object Streaming Pipeline for JavaScript

---

Stream.js is a lightweight (2.6 KB minified, gzipped), intensely tested (700+ assertions, 97% coverage) functional programming library for operating upon collections of in-memory data. It requires EcmaScript 5+, has built-in support for ES6 features and works in all current browsers, Node.js and Java 8 Nashorn. Before explaining how Stream.js works in detail, here's a few real world code samples.

LArray - Large off-heap arrays for Java/Scala

---

A library for managing large off-heap arrays that can hold more than 2G (2^31) entries in Java and Scala. Notably LArray is disposable by calling LArray.free or you can let GC automatically release the memory. LArray also can be used to create an mmap (memory-mapped file) whose size is more than 2GB

negative-array - Negative array index support `array[-1]` using ES2015 Proxy

---

JavaScript doesn't natively support the use of a negative index to get items backwards from the end, but with ES2015 Proxy it's possible. Take a look at the source to see how simple it is to implement and read this short article about it.Proxies are objects for which the programmer has to define the semantics in JavaScript. The default object semantics are implemented in the JavaScript engine, often written in lower-level languages like C++. Proxies let the programmer define most of the behavior of an object in JavaScript. They are said to provide a meta-programming API.

scour - Traverse objects and arrays with ease

---

Calling scour(object) returns a wrapper that you can use to traverse object. Use get() to retrieve values.Use go() to dig into the structure. It will return another scour wrapper scoped to that object.
