# Foreach

Foreach action is just a more readable way of handling iteration over an array. Only thing to keep in mind is that **Iterate over** is JavaScript expression, if you want to reference data from other actions you need to use **ctx** object. **Iterator variable** on the other hand is not an expression but is just a name for output value that will be stored in **ctx** object.

### Iterator variable

Iterator variable is not an expression but a name for where to store the currently iterating item. With above example first item will be `ctx.product = ctx.products[0]` and so on for each iteration.
