Top 13 Mistakes Committed By Angular JavaScript Developers
Keep a track on the count of Watchers Angular JS creates a watcher for every binding. Evaluation and comparison for previous bindings are done at each digest phase. In the end, the number of watchers comes out to be huge. Few watchers are okay but these watchers start getting troublesome when there are hundreds and thousands of them in the code eventually slowing down the performance of an application in the browser. ONE
Inability To Use The Available Tools Most of the developers do not utilize the available tools to their best extent. This is one of the most disappointing circumstances since it becomes necessary to utilise a tool sooner or later. For instance, Firefox and Chrome incorporate uncommon improvement strings that involve investigation, mistake yield and profiling. TWO
Not Compartmentalizing Properly Compartmentalizing your code is the core part of coding in Angular JS. When you work with MVC, the general concept is that you have a controller for a view. The controller is your rationale layer, and it’s imperative that inside this layer you make compact compartments for each area of your application THREE
Falling Back Into jQuery jQuery is a customary library for handling events and for making DOM Manipulations easier. However, AngularJS, on the other hand, is a framework that is used for the creation of scalable applications, testing and development of applications and hence it cannot be utilised in the amplification of HTML documents. FOUR
Angular’s horizon is seized to hold all the data that is required to show all the content of the page to the user. It is quite affable that permits writing of custom functions based upon the crowded content. Angular JS can be perfect specifically when it comes to appending functionality grounded on forecasted data like boasting a button based on user input. Improper Use Of Event Handlers FIVE
Don’t forget to Test It’s quite handy for the developers to compile and execute an application on their individual machines and presuming that it goes well with every other system out there. Not testing an application before their release is a common mistake among developers because they don’t understand the fact that different environments can instigate bugs. SIX
Fail to Utilize Batarang Batarang is an extraordinary Google Chrome extension which is employed for debugging and developing Angular JS applications. Batarang can be useful when operating on abstracting scopes where arguments are limited. Avoid the common mistake of not utilizing this tool to its full potential. SEVEN
Fixed Scope Binding Normally, Angular accompanies its very own degree settling rules. A simple usage of information sources limit to a model, for example, it can prompt a typical breakdown in the binding system. However, the complexities come down to making sure that the names are fully upskilled. EIGHT
Do Not Forget to Unsubscribe There are two scenarios where unsubscribing grows into a major risk – First, you ignite the lifecycle hook by yourself if it’s a service that you’ve subscription of and second, you stimulate the OnDestroy lifecycle hook if it’s in a constituent that you’ve subscribed. Keep a check on these to avoid any complications later. NINE
Declaring Everything With Anonymous Functions Assigning your functions and objects accounts for a tidy and maintainable code. This kind of well-maintained and documented code is easy to work with and can easily be divided into files. Not just this, such pieces of code have an increased testability. This makes it easy for the developer to maintain the application code and gives more expressibility to the code. TEN
Direct Manipulation of DOM This is the most common mistake that every new Angular JS developer commits. Whether it involves rendering SVG or refreshing a web page’s heading on a context changes, a developer decides to take the easy way out and makes changes to the DOM directly. ELEVEN
Not Using $applyAsync Because there is polling contraption to call $digest() in AngularJS, it is just implemented because of the subsisting directives. $applyAsync aids a lot in detaining the expression resolution to the next cycle of $digest(). There is both an automated and manual way to wield $applyAsync. TWELVE
Same Component In More Than One NgModule Declaring a component in multiple NGModule-s is one of the most recurrent mistakes among Angular developers that end up throwing an error right at your screen. This error occurs because one needs to mention each component in the scope of its own NgModule. THIRTEEN
AngularJS is an exceptional front-end framework. It’s one of the leading tools on the web for creating single page applications. And since it is scalable and backed by Google, you get plenty of support and guides to get you started. Developing is not just about writing error-free code, it’s about committing an error once and never repeating it. Instead of embracing the “fail fast, fail often” concept, one needs to learn from the mistakes of other developers and ensure that they rarely fail. At least, due to the same mistake. CONCLUSION
HAPPY TESTING!!
