Invokes a function once for each element in a collection, iterating from right to left.

## Notes

-   For dynamic array resizing, the only behavior made intentionally consistent with `forEach` (iterating from left to right) is when elements are pushed onto the beginning (end) of an array. In other words, for `forEach()`, `[].push()` behavior is consistent with `forEachRight()` `[].unshift()` behavior.

@param {Collection} collection - input collection
@param {Function} fcn - function to invoke
@param {*} [thisArg] - execution context
@throws {TypeError} first argument must be a collection
@throws {TypeError} second argument must be a function
@returns {Collection} input collection

@example
function log( v, index, collection ) {
    console.log( '%s: %d', index, v );
}

var arr = [ 1, 2, 3, 4 ];

forEachRight( arr, log );
