You can find Vanilla JS in Facebook, Google, YouTube, Yahoo, Wikipedia, Windows Live, Twitter, LinkedIn, eBay, Microsoft, Apple, Pinterest, PayPal, Reddit, Netflix, Stack Overflow and a number of other popular websites and platforms.
Interestingly, Vanilla JS framework almost reminds us of vanilla ice cream, because the framework is unmodified, and you are using the basic product as it is, without adding anything to it.
All you are doing is, you are using the framework with the most basic API functions of the JS interpreter. Naturally, any website that doesn’t use a framework will have to automatically use VanillaJs, and even if they do not use a framework, they do use certain features and algorithms of VanillaJS. The framework also allows you the full freedom of implementing whatever architecture you want to. You can also integrate this with your business logic, DOM manipulation logic, any other tools you want to connect.
Here’s looking at Vanilla JS with a couple of other languages
Vanilla JS Vs React: when you can use what
Vanilla JS does help you build powerful cross-platform applications and so on React, it is one of the most popular JS libraries, thanks to its flexibility and performance quality. React can break down the UI into smaller, reusable components that can be moved against each other. And it is this feature that acts as a winning edge over VanillaJS. For JS, it becomes very difficult to maintain the code if the application is large. In such cases, the UI will have to be updated regularly.
And that’s not all. To change the UI element, you will have to first find the element in DOM, and only then update it. This can be tedious when you have to change only a single element. React has a virtual DOM, and helps in bypassing the manual task. So in short, with Vanilla JS, keeping the UI in sync can be tough and painstaking.
Vanilla JS Vs jQuery
With jQuery, a lot of things can be easier for the novice developer, but there is no rule as such that says where to use Vanilla JS and where to use jQuery. However, iQuery is a huge time saver because it comes with several pre-written functions for which only necessary modifications have to be made.
If you are looking at multi-browser compatibility , then browser related errors are likely to happen with JS. But with jQuery, this is not an issue, because it works with all kinds of browsers; there will be no compatibility issues.
For JS, all the coding will have to be done from scratch, and novice developers might find that difficult and time-consuming. jQuery on the other hand, has several pre-written functions, and when necessary modifications are to be done, it could be definitely time-saving.
When you compare the two, Vanilla JS is way faster than jQuery, and depending on the operation, can even be 10 to 25 times faster.
Vanilla JS Vs Angular JS
So once again, the choice you make will be dependent on the requirement. If you intend to become a front end or a full stack web developer, then it is important that you know about Vanilla JS. The base of all frameworks will always be JS, libraries and frameworks will come and go, but JS is here to stay.
Proficiency with Vanilla JS will always make it easier to switch to jQuery, though the switch may not be very smooth.
