Document Summary

The homework 1 key is available on canvas. An array is a series of related values referenced by the same name. In javascript, the values may be any type (primitive or object) and do not have to be of the same data type. Each value in an array is called an element or member. Each element in an array has an address called an index or subscript. Indices are numbered from zero to one less than the number of elements in the array.
