JavaScript has two foundational types of values: primitives and objects. Though this sounds simple, misunderstanding their behavior leads to subtle bugs, performance issues, and confusion — especially when passing values around, mutating data, or optimizing code. Let’s dive deeper into what separates them, with clear examples and best practices.

In ES5, building strings often required clunky concatenation with + and escape characters. ES6 introduced template literals, which make string handling cleaner, more readable, and more powerful.
Linked lists are one of the fundamental data structures in computer science. A common interview question (and practical exercise) is how to take the last node of a singly linked list and move it to the front.
Let’s walk through the logic, example code, and why this operation matters.
