12/03/2022

Writing clean code is essential for any developer, but it can be especially important when coding with JavaScript. The language’s flexibility and dynamism mean that there are a lot of ways to write code – some better than others. To help you get started on the right track, here are 6 must-know tips for writing clean Javascript code:

1) Use Meaningful Variable Names:

Variables should have descriptive names so anyone reading your program understands what values they hold without having to look up their meaning in comments or other external documentation. This will make debugging easier down the line if errors occur as well!

2) Keep Your Code DRY (Don't Repeat Yourself):

Whenever possible try not to duplicate lines of codes - instead use functions where appropriate which can save time and effort later on during maintenance tasks such as bug fixes etc... Doing this also makes sure that changes only need updating in one place rather then multiple places throughout an application or script file(s)

.3) Break Up Long Functions into Smaller Ones:

Large chunks of logic may seem intimidating at first glance so break them down into smaller pieces by using helper functions whenever necessary; this way each function has its own purpose/task making it much easier to debug & maintain over time!

4) Leverage ES6 Syntax Features :

Take advantage of modern features like arrow functions, destructuring assignment syntaxes etc.. These provide more concise ways for expressing complex ideas while improving readability too – something everyone appreciates whether working alone or collaborating within teams!

5.) Comment When Appropriate :

Comments serve two purposes - helping readers understand why certain choices were made along with providing instructions about how specific sections work together overall . It's best practice though not always necessary depending upon context e g , adding unnecessary noise might do more harm than good !

6 ) Test As You Go Along :

Lastly don't forget testing ! Make sure all components interact properly before moving onto new ones by running unit tests regularly ; these could save hours worth Of frustration digging through source files looking For mistakes further down road after forgetting small details initially overlooked ... In conclusion following above mentioned tips will go long way towards creating robust applications written With highest standards both aesthetically pleasing readable manner."
