Variables, Parameters, and Functions

• Camel case: Generally.
  • Rarely you will find a leading underscore with variable/function name. It is intended to be used as private though not enforced in JavaScript.
• Upper case: If global variables or constants. May have underscores between words for readability.

class SoftwareDeveloper {
  constructor(firstName, lastName) {
    this.myFirstName = firstName;
    this.myLastName = lastName;
    this.name = _getName(firstName, lastName);
  }
 
  _getName(firstName, lastName) {
    return `${firstName} ${lastName}`;
  }
}
var dev = new SoftwareDeveloper("King", "Tchalla");
console.log(dev.name); //Good
console.log(dev._getName("King", "Tchalla")); // Bad

const THIS_IS_PI = 3.14;
function doSomething(arg){}

Classes

• Pascal Case: Names of classes and enumerations

class MyClass {}
namespace MyNamespace {}
public enum MyEnum {}
public interface IMyInterface {}
