In this overview, we have compiled a list of tips on mastering the level of JS proficiency that will allow developers to be in the loop with the latest technologies and tendencies.
Remember to cross-browser.
Different browsers may render the JS code differently, resulting in compatibility issues. To avoid those problems, any web application or website page should be tested on various browsers. There are solutions like LambdaTest that allow developers to test any page online on a special platform.
Keep an object-oriented approach.
Object-oriented programming treats complex things as simple objects. Classes represent shared characteristics of the objects and contain methods that are applicable to the objects of one class. Thus, the object-oriented approach allows developers to divide complex structures into manageable, simple chunks that are easy to read and understand. So, it is not a problem for a new developer to understand your code, to use it, and debug it if needed.
Testing is as important as development itself, so do not underestimate it. Testers and QA engineers are responsible for checking every input and field for bugs. This process ensures a quality product that will be thoroughly checked and will only bring positive performance experience to the users.
Make use of relevant tools.
Look into DOM.
The Document Object Model represents the HTML page as a tree structure. With so many frameworks and libraries available on the market today, determining what DOM is may feel a little out of date. However, it is better to be a bit old-school here. If you wish to become a true expert, you should get into the details. You should know what will follow the changes in the properties of your HTML code and how they will be reflected in the page structure. Without this knowledge, you cannot be called a master.
Be aware of memory leaks.
It often happens with JS that you reserve some memory through variables and objects, but you do not use it. As a result, you face the runtime slowing down and poor performance. To avoid such issues, make sure you maintain your code and use special tools in the browsers, like garbage collectors.
Study hard 2.0.
To become a master, you need to learn, practice, and do those two things on repeat. Even if you consider yourself an expert today, it doesn’t mean you will keep this title in two days if you stop constantly staying on the edge of a technological wave. Technologies are developing at a fast speed, but this is what we like about them.
