Understanding call, apply, and bind in JavaScript
Before diving into call, apply, and bind, it's essential to understand the this keyword. In JavaScript, this refers to the object that is currently executing the code. However, the value of this can vary depending on how a function is invoked:

thisrefers to the element that received the event.
