Always think of ways to make your app lighter and quicker. Usually, you can achieve this goal by limiting the amount of code in your app. One additional thing you can do is called minifying. This technique is based on eliminating all the useless elements that “clog” your code, e.g., comments and white lines. They can be useful to make the code more legible, but from the machine’s point of view – they are useless and just take up valuable space.
All the glitches and technical problems can slow down your app. It is always beneficial to run some tests in order to make sure that your app works flawlessly and that there is nothing that potentially holds it back. There are many tools that enable you to verify the way your JS app (and its code) works. One of them is CodePen. Remember, only a fully functional and trouble-free app can work truly effectively.
Obviously, your users want the app to load as quickly as possible. But does it mean that the entire app has to load so quickly? No! Some of the features and parts of the code can be loaded a bit later when the user starts to interact with the app. Of course, we’re not suggesting significant delay, but even 50-100 milliseconds can make a difference, thus enabling faster loading and operation of your app.
Although we mentioned several techniques in this blog post, they all come down to one thing – always try to make your app as light as possible and fully functional. Only error-free apps can work truly effectively and help you increase UX and gain more users. Before you decide to implement any of the changes, run some tests and see how your app performs right now. It will be a good starting point.
