When I started my journey as a computer programmer I had written my code in a various way. I met some condition and I just put the correct statement regardless of the general concept or something more deeply. “It works, that’s it” – and the code base grew and grew in time. Thousands of written methods later I had discovered that a lot of these little pieces of logic could look better if I reverse some condition within them. Unconsciously, I’ve started following the rule which I had later called the “fail fast” rule.
I realized I hadn’t had the one way to check conditions within the single method. Sometimes I let execution if the expression was true. Another time I had waited for the false result to show the error message before the main part of the code was executing. In my head, I discovered various styles of checking conditions.
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.
Loop is the basic construction in each programming language. All repeatable operations are being done using loops. I think you know how the basic loops like while, do and for work and when you should use one of them. But are you sure? Maybe should you use array functions?
How many of your operations in a loop rely on building objects based on the value? Or selecting only a few items from the array using a predicate? Maybe you use array values to calculate something? Whatever you do, read why you should replacing basic loops by array operations.
Among thousands of files on my computer, I have some with special meanings for me. Photos, videos, papers, and spreadsheets – they occupy dedicated places within my filesystem. That’s the problem – they exist only on my hard drive. However, I sometimes need a quick access to these files from my smartphone or other computers. The solution seems to be simple: migrating to the cloud. But what if I definitely don’t want to keep these files outside?
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.
Do you use constants in your code? Probably a lot. Even if you don’t define your own is highly probable that you use some constants defined by other libraries or a language itself. Constants are very powerful unless you use it in the wrong way.
In September, I wanted to try something new, so I started a simple project to check my abilities in UX and front-end development. The idea was simple — create customizable, reusable and highly accessible buttons. I have experience with front-end but I usually use CSS frameworks like Bootstrap or Foundation. But not now. I decided to design the whole page completely from scratch.
