CustomObjectUtils

A utility class to provide methods for safely accessing nested object properties. The class can be initialized to use either ES5 or ES12 (ECMAScript 2021) methods.

Initialization

To use the utility, you need to create an instance of the CustomObjectUtils class. By default, it uses the ES5 methods. If you want to use the ES12 methods, pass true to the constructor.

var utils = new CustomObjectUtils(); // For ES5
var utils = new CustomObjectUtils(true); // For ES12

Methods

safeAccess (ES5)

Safely accesses nested object properties.

• Parameters:
  • obj (Object): The object to access.
  • path (string): The dot-separated path to the property.
• Returns: The accessed value or false if not found.
• Example:

var myObj = { a: { b: { c: 42 } } };
var value = utils.safeAccess(myObj, 'a.b.c');
console.log(value);  // Outputs: 42

safeAccessModern (ES12)

Safely accesses nested object properties using modern JavaScript features.

Modern Features Used:

• Optional Chaining (?.): Allows reading the value of key within a chain of connected objects without having to explicitly check if each reference in the chain is valid.
• Nullish Coalescing (??): Returns the right-hand operand when the left operand is null or undefined.
