In the quest to create the fastest website, to look at on page issues rather then a deeper problem. If you’re noticing that your website is still running slow, even though you’ve optimize various on page elements, the practice time to dive deeper into the infrastructure of your website. In many instances, the culprit of your slow and sluggish website has nothing to do with Image optimization or any other on page components. Rather, the issue has to do with your website code.
While dealing with website code can be a complex and difficult process, if you try to fix your speed issues but have not successfully increased performance then perhaps it’s time to look under the hood of your website.
If you’re looking for one of the most effective ways to speed up your website, then you should take a moment and learn about JavaScript asynchronous loading. Wow this topic sounds incredibly complex, it’s actually not as difficult as it seems. Although, if you’ve never dealt with JavaScript then you may need to hire someone who is more well-versed with dealing in this coding language.
What is Asynchronous Loading?
In order to understand asynchronous loading, we must first explore the meaning behind this word. If you’re to think about objects moving in sync with each other this means that they move simultaneously. So, if we take this into consideration, the asynchronous loading means multiple JavaScript elements actually load the same time.
There are some obvious benefits of asynchronous loading, some of which include more streamlined file downloads and ultimately faster website performance. Although this performance enhancement techniques is appropriate for most situations and websites, there are some instances where this is not the best option.
Instead of going into the technical details of this performance enhancing technique, let’s briefly explore exactly how asynchronous loading can increase your website speed.
How Asynchronous Loading Boosts Website Speed
What do you think would perform faster, five in JavaScript elements voting one after another or having all five elements loading at the same time?
Did you go without saying that having multiple elements download at the same time, or asynchronously, resulted in much faster website. When this element is activated your HTML files will load as normal, but JavaScript Will only begin to execute its actions when the end-user approaches that section of the webpage.
So, how does this differ from deferred loading? While it may seem that these two separate techniques are relatively the same, they are actually quite different. Let’s take a moment and explore the difference between these two techniques, and see how you can utilize either or both in the quest to create a fast website.
Not Fast Enough? Try Deferred Loading
As mentioned earlier, asynchronous JavaScript loading is appropriate for most websites. While it may seem that deferred and asynchronous loading are basically the same thing, deferring your JavaScript execute the very specific result.
Essentially, when you select deferred JavaScript loading it basically means your entire HTML file loads on your visitors browser before allowing JavaScript, or any other scripting, is executed. This allows your website to appear in your users browser extremely fast, which gives the appearance of having superior page load speed.
While this technique is excellent for website visitors who don’t support asynchronous script loading, typically asynchronous loading offers greater speed increases. Therefore, if you truly want to create a fast website for all users, then establish both asynchronous and deferred JavaScript loading.
