Let me show how easy work with Jest is.
I remember how I was excited discovering how much frontend frameworks like AngularJS could make my work easier. Even though I was a strong backend-oriented programmer I decided to learn the concept of Angular. I dug into it at ease and I started using this tool in my daily work.
Since I changed my job I lost the opportunity to use frontend technologies regularly. However, I’m still fascinated about this part of software development and I follow trends and latest changes. Therefore AngularJS 1.x was officially abandoned I started looking for something new and fresh.
I didn’t look for a long time. When I first saw React library, I fall in love with it. I quickly caught the concept behind this tool, thanks to ubiquitous tutorials and examples. I read a lot about the flux pattern, redux, components but I didn’t chance to use them in something more ambitious than
<HelloWorld/> component. Till now.
ECMAScript 6 has an amazing feature called Arrow Function. It allows writing a function expression faster and smarter than traditional way (using function keyword). Worth to know, it’s not a one to one replacement for standard functions.
This kind of libraries (and frameworks) provide an another abstraction layer behind our code making the execution process more complex. It’s invisible until you’ll need to debug your code because of errors.
