requires the presence of a `t-key` directive, to be able to properly reconcile
renderings.
`t-foreach` can iterate on an array (the current item will be the current value)
or an object (the current item will be the current key).
`t-foreach` can iterate on any iterable, and also has special support for objects
and maps, it will expose the key of the current iteration as the contents of the
`t-as`, and the corresponding value with the same name and the suffix `_value`.
In addition to the name passed via t-as, `t-foreach` provides a few other
variables for various data points (note: `$as` will be replaced with the name
passed to `t-as`):
In addition to the name passed via t-as, `t-foreach` provides a few other useful
variables (note: `$as` will be replaced with the name passed to `t-as`):
- `$as_value`: the current iteration value, identical to `$as` for lists and
integers, but for objects, it provides the value (where `$as` provides the key)
- `$as_value`: the current iteration value, identical to `$as` for arrays and
other iterables, but for objects and maps, it provides the value (where `$as`
provides the key)
- `$as_index`: the current iteration index (the first item of the iteration has index 0)
- `$as_first`: whether the current item is the first of the iteration
(equivalent to `$as_index == 0`)
