pass by reference

In JavaScript, the way values are passed depends on whether they are primitive types or objects. Primitive types, which include numbers, strings, booleans, null, undefined, and symbols, are passed by value. When a primitive value is passed to a function, a copy of that value is made, and any modifications made to the copy will not affect the original value. For example: const increment = num => { num = num + 1; } const num = 2; increment(num); console....

What sets primitive types apart from objects in JavaScript? Let’s take a closer look. First, let’s define what primitive types are: Strings Numbers (Number and BigInt) Booleans (true or false) Undefined Symbol values While null is considered a special primitive type, calling typeof null actually returns 'object', even though it is a primitive type. In JavaScript, anything that is not a primitive type is an object, including functions. Functions can have properties and methods assigned to them....
