/**
* Invokes a function once for each element in a collection and updates the collection in-place, iterating from right to left.
*
* ## Notes
*
* -   For dynamic array resizing, the only behavior made intentionally consistent with `inmap` (iterating from left to right) is when elements are pushed onto the beginning (end) of an array. In other words, for `inmap()`, `[].push()` behavior is consistent with `inmapRight()` `[].unshift()` behavior.
*
* @param collection - input collection
* @param fcn - function to invoke
* @param thisArg - execution context
* @returns input collection
*
* @example
* function scale( value, index, collection ) {
*     console.log( '%s: %d', index, value );
*     return value * index;
* }
*
* var arr = [ 1, 2, 3, 4 ];
*
* var out = inmapRight( arr, scale );
* // returns [ 0, 2, 6, 12 ]
*
* var bool = ( out === arr );
* // returns true
