An array is a data structure that stores a collection of elements, each identified by an index or a key.
-
Arrays provide a way to organize and access elements in a sequential manner.
-
Array indices in JavaScript start at 0. The first element is accessed using index 0, the second with index 1, and so on.
const arr = ['a', 'b', 'c', 'd'];
console.log(arr[1]); // b
