Writing performant code is not enough as a developer. We need to ensure that it is readable as well. And it is rare that an API change in a language introduces readability. Numeric Separators are one such rare change. Why numeric Separators? Reading this takes a few seconds: Counting the...
JavaScript promises do not have any time associated with them. We can use a .then() function and wait until the promise is resolved or rejected. We can even await it, and either of those works if the async task finishes in a reasonable amount of time. But in the case...
Having consistency and enforcing coding standards becomes very important as an application scales. It becomes important to automate the process to ensure quality standards and make the application maintainable. ESLint and Prettier can be used to define these standards, but we also need a tool to enforce them. Husky provides...
Writing conditional expressions is pretty easy to do. But there is room for improvement in the way we have been doing it. And with the flexibility that JavaScript provides, we can replace conditionals with clean code by using some good practices. And it can lead to more maintainable code. Let...
Every now and then, you come across a JavaScript feature that vastly changes the way you write it. Destructuring, arrow functions, modules have been some of those features for me. Optional chaining is going to be the next one on that list for me. Optional Chaining is in stage 4...
The process to format a number as currency can be a tedious task. It feels like a small task, but the number of lines and the edge cases can keep on increasing when considering factors such as internationalization and different formatting standards. Luckily, ES2015 introduced an internationalization API which can...
EcmaScript 2015 introduced yet another feature that has not been used widely yet. A JavaScript proxy allows us to wrap an existing object with a layer. The layer can provide us with capabilities such as the interception of attributes and methods. And this can be done even if the properties...
I was recently working on a project in which I was trying to use a shorthand notation for destructuring assignment of a variable. I was researching different ways of getting a specific scenario to work. And while doing that research, I found that ES2015 had added 3 new object initialization...
