JavaScript arrays are untyped: The elements of an array can be of any type. For example: string, numeric value, Boolean value, and so on. And each of the 1 elements in the array can be of different data types.

JavaScript arrays are dynamic: As needed, you can dynamically add, delete, check, and change elements in an array.

An important element of an array is the index of the array, with each of the 1 elements in the array having 1 corresponding indexes in the array, also called the subscript of the array. The index value starts with the number 0. We can add, view, modify, and so on to the array by index value.

There is also: every 1 array has 1 length property, which represents the size of the array. The length of the array refers to the number of elements contained within the array.
