My name is Ilya / and I’m a professional JavaScript developer / with experience in both / front-end and back-end Areas. For over 3 years,/ I’ve been doing web development using popular frameworks / such as Angular, Meteor, Node.js and the other related technologies.

My name is Oleg and I am a Front End Engineer, working in Web Development for the last 4 years. I am passionate about Javascript and I believe that this language has changed the programming world.

After some portion of theory it will be a good practice to do some practice! So today we’re going to build weather widget with auto update function and simple chart that will be fully built using RxJS. Take your knowledge of base concepts, that we’ve studied on previous lesson and let’s go!

The methods that are covered in this video are map, filter, reduce, take/skip and distinct. Most of them are array-like primitives they will give you the basis of your further work with RxJs and introduce main instruments from this large swiss knife!

Hello, everyone! Last time we have discussed how to use vagrant boxes. Now we are going to make our own vagrant box. This presentation will be useful for big teams starting from 15 developers or just for geeks from dev ops world.

Our today’s topic is a library for working with streams and events. It’s RxJS and it represents the idea of reactive programming. In the simple words, the meaning of this idea semantically is a representation of all operations as the stream, more specifically, as the sequence of events. Programmatically it means for our usage of two patterns: iterator (for establishing of the sequence itself and going through this one) and observer (for changes propagation).

From my experience many times customers asked me to install new environment for myself, help newbies to set the same environment. Another case was to upgrade software packages, e.g. Postgres 5.4 to 5.5. These tasks are not the complexity of ‘rocket science’ but if you are front-end developer it can take much of your time. The best is to give DevOps work to DevOps engineers.

Use when you want to select between different algorithms in the process of task resolving. So basically all that you need to realize this pattern are strategies (each of them in the separated component/class, but with the same interface) and strategy selector (decides what strategy is more effective at the moment and uses it).
