The assignment needs to be in jsfiddle

The HTML and Javascript must be separate

Write a program that will take the phrase, create bins for each word, and then record the instance position of each word in the bin. It will then output each bin (word) and the locations of the word in the phrase. So if the input was;

I want what I want and I know what I want.

The output would be;

I: 1 4 7 10

want: 2 5 11

what: 3 9

and: 6

know: 8
