​​Validation of data is an interesting topic, we tend to write code that looks really horrible in the sense that it contains a lot of checks. There are different situations when we need to perform these checks like validating a response from a backend endpoint or maybe verifying what goes into our REST API won’t break our code. We will focus on the latter, how to validate our API.

​​Today we’ll be making a ‘to-do’ website… with some different features.
For the front-end, we will be using React.js. For the back-end and storage, we will be using the browser’s local storage. This lets us save data so that next time we open our site, we can access the data we saved earlier.

​​Exactly one year after the first beta of iOS 11.3, Apple released last week the first beta of iOS 12.2: the first version since PWA support that responds to all the critics by offering solutions to the two biggest problems on PWAs on iOS. So yes, they took a whole year to say “we are working on this.” But wait, not so fast, I’m not saying yet that the solution is a good one. Let’s see 😬.

​​​​Pure functions are easier to read, understand, test, debug and much more. You may have already heard all of that before. The questions are: what are these pure functions? how do they look like? or can we write the whole application using only pure functions?

​​Template literals in JavaScript are basically regular strings on roids. The syntax for writing them is with backticks instead of regular string quotes. You can place expressions into those template literals which will be evaluated and replaced with the resulting values of those expression

​​Before event-driven programming became popular, the standard way to communicate between different parts of an application was pretty straightforward: a component that wanted to send out a message to another one explicitly invoked a method on that component. But event-driven code is written to react rather than be called.

​​The history of computing can be divided into an Old Testament and a New Testament: before and after electronic digital computers and the codes they spawned proliferated across the earth. The Old Testament prophets, who delivered the underlying logic, included Thomas Hobbes and Gottfried Wilhelm Leibniz. The New Testament prophets included Alan Turing, John von Neumann, Claude Shannon, and Norbert Wiener. They delivered the machines.
