In a previous blog post we explored how to perform immutable operations to update objects using Object.assign(). This time we are going to explore how to perform immutable operations on an array of objects which is a common pattern in Redux. If you wan’t to learn more about Redux, take a look at the excellent training course “Getting Started with Redux” by Dan Abramov, the creator of the library.

Introduction to the Typescript Transpiler
Typescript is the new kid on the block, a newly attempt to bring order to the javascript chaos. ES6 is around the corner and is a fantastic step forward for frontend development (classes!) but it will take years to be fully implemented in all major browsers. That’s when Typescript comes to the rescue. Typescript goal is to be a superset of ES6 that, in addition to all the new stuff that the standard is defining, will add a static type system. Typescript has also a transpiler that converts our Typescript code (i.e. ES6 + types) to ES5 or ES3 javascript code so we can use it in today browsers.
