Function: foreach

- [Instructor] Another loop function…is the FOREACH function.…The FOREACH function works with the values in a list…and it will continue looping through or iterating through…each item in the list…until all items have been looked at.…We first provide a list to the FOREACH function.…Notice the list that we have here is just numbers.…It's one, two, and so on until six.…That is one of the arguments in our FOREACH function.…The first argument is a temporary variable.…

So temporary, in fact…that as soon as the FOREACH function ends XVAR goes away.…It's not even listed as a local variable.…What happens is every single time FOREACH loops…it takes one of the values in the list…and assigns that value to the XVAR variable…or whatever name that we put here.…We see in our code here what's going to happen.…It's going to loop through each one of these numbers…and it's going to identify whether or not…the number is less than four.…

If the number's less than four…it's simply going to type that out.…If the number's four or greater…
