6 JavaScript Concepts That Are Often Overlooked by Beginners

Crucial overlooked features that developers should be aware of

There is currently a huge number of beginners learning JavaScript, especially during this quarantine period. This can also be attributed to the fact that there is ample demand for web developers in the market and JavaScript is one of the core skills of most web developers.

Most beginners utilize the excellent free resources that can be easily found online to start their JavaScript journey. But they often skip or overlook some important concepts they find confusing or difficult to understand. Little do they know that these overlooked concepts are some of the most important concepts in JavaScript.

Let’s have a look at my pick of the top 6 most overlooked JavaScript concepts.

Closures and Higher-Order Functions

Closures are one of the trickiest JavaScript concepts to understand as a beginner. But once you have learned, you will begin to see the magic of JavaScript. Ample resources are available online. Just make sure you take the time to understand closures.

A closure would give you access to an outer function’s scope within the inner scope. JavaScript closures are created every time a function is created, at function creation time.

Higher-order functions on the other hand are functions that take other functions as arguments or return functions as a result. Higher-order functions allow composition to unleash the fullest power. You can create smaller functions that take care of only one task and then construct complex functions with the help of these smaller functions. This will result in an increase in code reusability as well.

This also reduces bugs and makes our code easier to read and understand.
