reference vs primitive

Comment

// Primitive
// values are stored directly on memory
// modifying such data will create new data instead and replace original

const number = 1;
or
let number = 1;
number = 2; // replaces 1 with 2 (replaces 1)


// Reference
// they represent a location of data in a memory
// so, instead of replacing data, you are editing it.

const numbers = [1, 2, 3]
numbers.push(4); // memory location is the same, but gets edited and updated

reference type vs primitive type

Comment

// The value of primitive data types are directly stored in the memory.
// For example if int a is initilized to 11, then 11 is directly stored
// in the memory.
int a = 11; // Primitive Type 

// Reference types on the other hand are a reference to values in the
// memory. For example Integer(11) creates a reference in the memory
// whever the value 11 is stored and passes that memory reference/
// (address) to the variable.
Integer b = new Integer(11); // Reference Type
