7 Recommendations to Improve the Reliability of Your JavaScript Code

In 2020 JavaScript is considered one of the best reputed technical tropes in the world of coding. The willingness of many companies to try to replace it and the continued unsuccessful attempts show that many people out there feel very comfortable with JavaScript despite its age. The case grows stronger when we notice how JavaScript is one of the essential components of HTML5 technologies along with other languages such as JQuery, CCS, and Python. The following are some recommendations we have gathered around the web from some of the most reputed blogs on the topic to help you make your JavaScript code more reliable and efficient. 

Learn Async Programming

When you create an app using JavaScript, you need to make a lot of calls to APIs to get all the data you need. The best way to make this task more productive is by using middleware to handle every task. Since JavaScript is single-threaded, you can find a lot of sync components to help you lock up the app and make it work just as you need. You can handle this by using the feature named asyinc.js to manage the code on queue and execute another task when required. Async.js can be tricky because if it’s not used correctly, it can affect the performance of your utility, but it’s also pretty resourceful to help you create the app just as you want it. 

Do your Best to Trim your HTML Code

The most intimidating aspect of JavaScript is how it looks in raw form. HTLM code is not a very big, complex monster. But the build determines the duration of each process that goes through it. Queries are managed faster on a streamlined code. You can modify DOM objects faster with your app if you trim your code to half. Keep it simple! Doing some code review as a service can help you make your app or website much better! You can start by taking out all the non-essential <span> and <div> tags.

Manage Your Variables

In JavaScript, you can define functions with certainty, but they can be affected by variables that determine the purpose even in the way it’s stored. When you name a function, the browser works with a lookup scope the increases the chain reaction of the code. This determines the time you can access the programmed feature. Long story short, this can have some negative effect is the time it takes for your utility to access a global variable. If you define them on point at the moment of writing the code, you won’t have to worry about this.

Use as Many Pointer References as You Need

When you work on JavaScript, there is a great way to keep the number of DOM transversal trips low. You need to store pointer references for browser placements during installation. The more references you include, the less likely your DOM will change. You will also make the speed response of the site much faster. You can also do this with local variables using reference objects, but it takes a little bit more time. 

Use Gzip Compression Protocols

Gzip is probably the best software for file compression out there is incredibly suitable for servers and large data storage. The most popular browsers work with it, and they make data transition easier to send a quicker, more effective response. This suits JavaScript like a ring since most files created with this coding language are pretty significant. Gzip protocols are excellent to reduce lag, save bandwidth, and improve the performance of your utility.   

Get Rid of Unnecessary Loops

JavaScript is not good at looping. As a matter of fact, no coding language is built to stand over looping since this puts a lot of strain on the browser’s capacity to load a proper response to your utility. Using loops is not frowned upon, but by avoiding them, you’ll make all processes faster and reliable. The tricks to prevent looping are many, and most of them are pretty useful, such as storing your arrays in different variables to avoid long iterations of every loop. This is also pretty good to make your finished code run smoother.   

Get Backup from the Cache to Improve the Performance of the Code

When you write code that makes good use of the cache of the physical device, you can make the scrip read the same process over and over without having to load everything to work correctly. Although the best code is the one that provides minimal load times, by having the browser store objects in the cache, you will increase the performance time of your app or utility to the best of its capabilities. 

There is a lot more you can do with JavaScript code to make it more efficient. If you manage an excellent object interaction with the host of the browser you are targeting, the code can get a little crazy. That’s why it’s important to code for a very specific environment, and that’s also the reason why you see different versions of apps, extensions, and such for different browsers and OS. Storage will always be an issue, but they make load times a breeze for JavaScript, so its best to put this feature to use to enhance performance.
