Any time you see string1.indexOf("string2") it is checking the position of "string2" in "string1". If it's not found, it returns -1 because 0 is the first position.

Hello Chuck,

Is there documentation on these string functions?

Thanks,

Chad

Here you go!

These are basic javascript functions.

indexOf() refers to the Index where that particular string is found.

var string = testGaurav

Here: indexOf("Gaurav") returns 4.

var string = Gaurav

Here: indexOf("Gaurav") returns 0.

var string = testtest

Here: indexOf("Gaurav") returns -1, since the string is not found.

Which means, if string is found anywhere, it returns value starting from 0.
