on every element. Returns true if all iterations
return true . Otherwise, it returns false .
filter(testFn(element,
index, array))
JavaScript 1.6
Iterates over the array, executing testFn()
on every element. Returns a new array of
elements that pass testFn() .
foreach(fn(element,
index, array))
JavaScript 1.6
Iterates over the array, executing fn() on
every element.
