The Difference Between Values and References in JavaScript

Read Original

This article details the concepts of passing by value and by reference in JavaScript. It explains how primitive data types (numbers, strings, etc.) are passed by value, creating copies, while objects (arrays, functions, plain objects) are passed by reference. The post includes code examples to illustrate variable assignment, mutation, and comparison behavior for both categories.
