---Returns the elements from the given list. This function is equivalent to

---Executes the given f over all elements of table. For each element, f is called with the index and respective value as arguments. If f returns a non-nil value, then the loop is broken, and this value is returned as the final value of foreach.

---@version <5.1, JIT
---
---Executes the given f over the numerical indices of table. For each index, f is called with the index and respective value as arguments. Indices are visited in sequential order, from 1 to n, where n is the size of the table. If f returns a non-nil value, then the loop is broken and this value is returned as the result of foreachi.
