JavaScript Array get key

In this Tutorial we want to describe you a code that help you in
understanding JavaScript Array get key. For this we implement JavaScript as
Scripting language. We have taken an array that creates and initializes an
associative array including different three elements. The elements in this
array are addressed using the key strings("R", "I",
and "N") instead of an array element number (0, 1, or 2). In the
example given below ,array["R"] returns
you "ROSE". This provides you to create and use arrays with more
different addresses schemas.. The given below code uses for loop to iterate this
array..
