Name your variables clearly
Anyway, let’s assume you have to complete the task that involves your coding skills. The first tip to know is to name your variables clearly. It will help you navigate numerous documents (provided your task is extensive) and don’t spend a lot of time looking for a specific variable.
Watch your code
Comments are an excellent way to make your code understandable for others. They are also useful because they help you remember what you intended to do with specific lines. However, there is a thin boundary between a helpful comment and an overwhelming text block, and it is easy to compose a hard-to-understand comment. When creating a comment, ensure making it compressed and accurate. And remember, don’t spawn myriads of comments. Having them under every line is a wrong strategy.
It enforces type safety
It mitigates and accelerates refactoring
If you are more skillful in programming, remember how painful it is to refactor a JS application. TS makes the refactoring procedure way faster, easier, and above all, safer.
It makes communication effective
Students often work on collective tasks. Programming is no exception. Once you break down the assignment into chunks, you don’t have to notify your colleagues that you have completed your part. Nor do you need to reach out to them seeking support or clarification. TS basic request feature lets others know about your progress.
Don’t overuse nesting
Nesting is widely used when learning the ropes of JS. It helps read and understand the code, and it allows for powerful yet simple programming. Nesting reduces the amount of code needed while helping a person to debug and edit the code. However, overusing this feature results in a clumsy and hard-to-follow code. And needless to say that no one wants to read large horizontal lines.
By looping, programmers use code in the document repeatedly. And the more extensive your task is, the more looping you will need to do. However, looping loads the code, which takes JS plenty of time to read every array. To effectively use loops, store the length value in a different variable or add a second variable before looping the array.
Employ modern features
promises, async and await
It is a common fact that JS doesn’t work with asynchronous code. Whenever anything similar emerged in the code, it led to a callback that didn’t let users move forward with coding. Thanks to promises, it has changed tremendously. Promises allow you to write asynchronous lines and avoid the most problems (some of them still might remain). To eliminate chances of a callback, use async and await.
Sometimes, you will have to use commands for variable scope. If you have ever done that, you can find it daunting and time-consuming. But don’t rush to sigh if your task requires you to do so. A command called const will perform the same actions much faster and provide you with sound code.
Check your code
Checking the assignment before submitting it is a must. Before sending your task to the teacher, test it and fix all the bugs and errors. Fortunately, you don’t need to walk through the entire code looking for inaccuracies. The following tools will help you check your code and correct any error or bug:
- Sinon: Analyzes various elements of code
- Ava: Tests every line thoroughly and precisely
- MochaJS: Tests lines and provides reports
