So, what does that mean, and what can it do for my TypeScript code? First, by static, you don’t need to run or even compile a program to parse it. …

We’ve all written some pretty terrible code in our day, but what if there was a way to write better code from the start? — That’s where VSCode extensions come in. I have selected and configured only five extensions for you. With this minimal set, you’ll be able to write cleaner code. Keep reading to know how to avoid common mistakes that lead to poor readability or unmaintainable code bases. Of course, there are a…
