@QAThoughts This video explains about how to work with Arrays in javascript. Please watch previous videos to get understanding Objects and Functions in JavaScript
Array - Variable that can hold more than one value. Multiple values can be stored in single array variable. Arrays are flexible and can store multiple data types within the same array, including numbers, strings, Booleans, and even other objects
When values are stored in an array, they are assigned an index, starting from 0 for the first element. The video demonstrates how to declare arrays in two ways, and how to access specific elements by referring to their index within square brackets
It also shows how to find the number of elements in an array using the .length property - This .length property is particularly useful when looping through an array to access all its elements. Also it illustrates this with examples of a standard for loop, a for...in loop which iterates over indices and a for...of loop which iterates over the values directly
