What are conventions?

πŸ‘‰ Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language.These are guidelines for software structural quality.

PascalCase

PascalCase is a naming convention in which the first letter of each word in a compound word is capitalized. Software developers often use PascalCase when writing source code to name functions, classes, and other objects.


πŸ‘‰ Example :

var UserName = "Adarsh";
Enter fullscreen mode Exit fullscreen mode

camelCase πŸͺ

camelCase describes the practice of writing phrases such that each word or abbreviation in the middle of the phrase begins with a capital letter, without intervening spaces or punctuation.


πŸ‘‰ Example :

var userName = "Adarsh";
Enter fullscreen mode Exit fullscreen mode

snake_case 🐍

Snake case is the practice of writing compound words in which the words are separated by one underscore character and no spaces. The first letter is either upper- or lowercase. It is commonly used in declaring variable names, function names, and sometimes computer’s filenames.


πŸ‘‰ Example :

var user_name = "Adarsh";
Enter fullscreen mode Exit fullscreen mode

kebab-case 🍒

all letters are written in lower case and the words are separated by a hyphen or minus sign. The kebab notation is often used as a convention for naming filenames.


πŸ‘‰ Example :

var user-name = "Adarsh";
Enter fullscreen mode Exit fullscreen mode

Good high level overview!
For more detailed JS naming conventions, I highly recommend to refer to the Airbnb JavaScript Style Guide

Airbnb is what i personally prefer β™₯️ but beginners find it overwhelming when they see es6 , react or even something like arrow function, I'll definitely recommend my readers to go through Airbnb Guide at the end of seriesπŸ€“
