22.1: Introduction to Arrays in JavaScript<\/strong><\/h3>\n

An array\u00a0a regular data structure\u00a0comprises\u00a0individual elements\u00a0that can\u00a0be referenced\u00a0to one or more integer index variables, the number of such indices being the number of dimensions\u00a0or number of elements\u00a0in the array.In\u00a0JavaScript, an array is usually represented using the format\u00a0arrayName[ i ],<\/strong> where i is the index or subscript which represents the position of the element within the array.<\/strong> The array always starts with the zeroth element. For example, an array A of 8 elements comprises elements\u00a0 A[0], A[1], A[2], A[3], A[4],A[5], A[6], A[7].
