/**
 * Passes every element of an array into a function and accumulates the result.

 * For example:

 * returns 10
 *
 * @param {goog.array.ArrayLike} arr The array over which to iterate.
 * @param {Function} f The function to call for every element. This function
 *     takes 4 arguments (the function's previous result or the initial value,

 *     array itself)
 *     function(previousValue, currentValue, index, array).
 * @param {*} val The initial value to pass into the function on the first call.
 * @param {Object=} opt_obj  The object to be used as the value of 'this'
 *     within f.
 * @return {*} Result of evaluating f repeatedly across the values of the array.
