JavaScript Tip 💡

Avoid default exports.
You will get a way better developer experience, especially if you're using TypeScript.

If you're using CommonJS, you can spare yourself the annoying "
.default" when you require.

It's a great coding habit ✌️

What gets logged in the following code?

let i = 0; const arr = new Array(5); arr.forEach(() => i++); console.log(i);
Array methods like map, filter, reduce, forEach, etc take a callback as the first parameter, which is executed for every element in the array. The Array constructor, when given an integer between 0 and (232 - 1), will return a sparse array, which has a length property equal to the given integer. The returned array is "sparse" because its slots are empty; it does not have any own-properties, other than .length. (In contrast, the array [undefined] does have an own-property of 0, even though the value at that property is undefined.)

💛 JavaScript tip 💛

One common issue when dealing with JSON de-/serialization is with date strings. You serialize a date but then deserialize a string. You simply lose type information.

Gladly, there is a fix for that, a reviver function, and here is how you use it!

TypeScript Tip 💡

Use the utility type 'Record' to make an object indexable, instead of typing it out manually.

It's more clean, and becomes handy if you want to map the properties of one type to another.

40+ JavaScript Projects For Your Portfolio [With Video links!]

In the front-end space, a lot of frameworks exist: React, Angular, Vue, just to name a few. Every single one of them is awesome and without them, front-end development wouldn’t be in its current state. But what those frameworks, besides all their differences, have in common is that they are all based on JavaScript. Yep, good ol’ JS!

JavaScript is what runs the web today, no doubt. And for every  front-end developer, no matter if already experienced or at the start of their careers, it’s mandatory to know the basics of JavaScript, HTML, and CSS.

Frameworks come and go, but JavaScript will stay! But what's the best way to practice JavaScript? The best answer I can give you is to build projects!

JavaScript Projects

JavaScript projects are guided tutorials or javascript project ideas that help you sharpen your skills by building real applications, websites, games, components, etc.

Sometimes you will find project ideas that just contain a title and a few sentences of what you should build.

Example: Build a counter with JavaScript that counts down the hours till the end of the year.

This format is good if you already have some experience and are just looking for some input.


JavaScript Projects for Beginners

However, if you are new to web development, it's often better if you look for JavaScript project examples with source code or specific JavaScript projects for beginners.

These often contain a running demo application, a GitHub repository with the source code, and a step-by-step guide on how to build the project.

JavaScript Practice Projects

So for you to gain practice, I have listed nine awesome javascript project ideas that you can do to refresh your skills, learn new things about JS, and stay relevant in the future. All of them are based on pure JavaScript, some HTML, and some CSS. You can add them to your portfolio, show them to recruiters or potential employers, or keep them in your GitHub as references for future work. To be clear: This is not meant to teach you everything about JavaScript. There are perfect courses for you covering JS from A-Z. This is for building things. Getting your hands dirty. Working on your muscle memory.
