MSDN's Kyle Pennell introduces the new ES6 collections Map, Set, WeakMap, WeakSet, explaining how and when to use these new data collection types.
M. David Green uses filtering to limit a data set & chaining to combine the results with map/reduce. The result—clean code that performs complex operations.
Ashraff explains how to create streams and then transform them using three widely used higher-order methods named map, filter and reduce.
M. David Green demonstrates how using the functional programming techniques of mapping & reducing can lead to cleaner code which is easy to read & maintain.
A quick tip from Jezen Thomas on how you can stop writing for loops and start using map — a technique that makes for cleaner, more readable code.
This article looks at two new data types, Map and WeakMap, introduced in ECMAScript 6.
