Best Tips For Junior Front End Developer

If you want the best tips for junior front-end developers, then you will also want to know how to test Angular and React components thoroughly. As a junior front-end developer, the most important part of your job should be to understand how these two dynamic frameworks work. 

You need to know the fundamentals of how they work, what browsers are capable of them, and how to properly set up Angular and React components on the page. This article will go over some of the best tips for junior front-end developers to make sure that their codebase adheres to recommended design practices.


Angular and React are powerful frameworks that, when combined with a quality-testing tool, can create testable, maintainable codebases. Because of the dynamic nature of these frameworks, a test suite is necessary for comprehensive functionality testing.

 Luckily, there are a number of great testing tools for Angular and React out on the market today. Here are some of the ones that I would recommend.


When it comes to testing Angular components, there are a couple of different options that I would recommend. First, there is the manual testing option, which involves writing unit tests, which assert specific behaviors of each Angular component. Manual testing is definitely the best tip for junior developers to use because it is the most time-consuming and tedious. With a manual test, you’ll likely find that Angular gets really stuck while running, making it incredibly hard to refactor the code. However, if you’re already comfortable using Angular, or if your project utilizes many of its features, then this may not be a big problem.


Another option that I would recommend for junior developers is to use an Angular Mocha plugin. Angular Mocha makes debugging Angular tests easy by displaying a visual tree of component trees. When the developer clicks on a component, it will display a list of its ancestors in alphabetical order, which can be helpful for finding bugs more easily. The downside to Angular Mocha, however, is that it doesn’t support the experimental ES6 functionality, so you may want to consider using a different testing framework.


Speaking of testing, one of the best tips for Angular and React developers to use is to use Chrome inspector. The Chrome inspector allows the developer to visually see how each element of the page is being rendered, as well as how each click on the element is being handled. This is particularly important when working with large numbers of elements. Another issue with Angular and React is that they both use a complex internal state, so testing for each of these component interfaces often requires a deep understanding of JavaScript.


One of the best tips for Angular and React developers is to use an instrument called Chai. Chai is an open-source testing platform written in JavaScript that works well with these frameworks. Chai provides a graphical user interface for testing Angular and React components and even provides official Angular and React documentation. There are several different versions of Chai, depending on your operating system, and it’s worth looking at all of them to see which one works the best for your project. Since the official repository does not yet contain Chai, some developers have made their own unofficial Chai repository, based on Angular and React, that they publish on Bitbucket.


Another useful tip for Angular and React developers is to use libraries and tools that allow them to create reusable components. One popular tool for doing this is called angularfire, which allows the developer to create reusable components in just a few minutes. The tool works by re-wrapping an Angular component in a function that Angularfire calls to perform all the complex logic for the component. Many tools, such as CodeIgniter, also perform some of the same functions, but they’re typically less complicated and allow for higher scope in a function definition.


If you’re a junior front-end developer and you want to learn Angular and React, the best tips for you are going to be from someone who is just starting out themselves and has little experience with these two technologies. However, if you have experience, a handle some Angular and React development on your own, then you’ll be able to take advantage of the best tips for junior front-end developers so that you can build up your skills quickly and start making more money as a result. After all, there are no advanced technologies available that will enable you to write actual applications.
