Naming Convention in JavaScript. Case Styles

What is meant by naming convention?

Naming conventions propose logic when it comes to naming identifiers. No one imposes these naming conventions as rules, however, they are generally considered in the JavaScript community.

Different Case Styles:

Case explains that how characters are formatted within a word or phrase.

Following the cases that are usually used in Javascript:

UPPERCASE: In the upper case all the letters are capital, for example, HOURS and PI. Constants are usually written in upper-case.
lowercase: In lower case all the letters are small, for example, name and age. Variable names having only one word are usually written in lower-case.
camelCase: Writing phrases such that each word or abbreviation in the middle of the phrase begins with a capital letter, for example, variableA and studentsCount. Functions are usually written in camelCase notation.
PascalCase: Writing phrases such that each word in the phrase begins with a capital letter, for example, HumanBeing and StudentsCount. Classes are usually written in PascalCase


              123456789101112131415
            
//lowercase
let name = 'bob william';
console.log(name);

//uppercase
let NAME = 'PAUL ANTHONY';
console.log(NAME);

//camelcase
let fullPrice = 1000;
console.log(fullPrice);

//pascal notation
let SoftwareDeveloper = true;
console.log(SoftwareDeveloper);
