returned by this function will be automatically passed to the next item as the first argument. The first iteration occurs on the second item of the array, so the first parameter is the first item of the array, and the second is the second item of the array.You can use the reduce () method to perform an operation that evaluates the sum of all the values in the array, such as:var values = [1,2,3,4,5]; var sum = values.reduce (function (prev, cur, index, array) { return prev + cur; }); alert

the for loop, which iterates all entries of the iterable object. the expr of the front edge is applied to each member of the sequence. The final result value is the list generated by this expression. iteration variables do not need to be part of the expression. >>> [X ** 2 for x in range (6)][0, 1, 4, 9, 16, 25] >>> Seq = [11, 10, 9, 9, 10, 10, 9, 8, 23, 9, 7, 18, 12, 11, 12] >>> [X for x in seq if x % 2][11, 9, 9, 9, 23, 9, 7, 11] 8 What is the focus of p
