ForEach(array, function)

Description

ForEach calls function on each element of array.

The BASIC implementation of this function is consistent with VBScript: element is a simple variable which gets the value of each element in the array sucessively.

If you're using JavaScript, the JavaScript specification is fully supported.

Example

// ForEach Example

var School;
School = new Array("Principal", "Mr. Garrison", "Chef");
School.forEach(listItem)

function listItem(item){
  NSB.Print(item);
}

Rem ForEach Example
Dim School
School = Array("Principal", "Mr. Garrison", "Chef")
ForEach(School, listItem)

Function listItem(item)
  Print item
Next

Output

Principal
Mr. Garrison
Chef
