Add conditional in a for loop

Question

I need to add a separator if there are a multiple of types. How can this be done in a for loop?

{% for type in entry.buildType %}{{ type }}{% endfor %}

The outcome is similar to a breadcrumb nav, with an added "/", however the separator should only be placed in between - not for the last.

Answer 1

{% for type in entry.buildType %}
{{ type }}
{% if not loop.last %}/{% endif %}
{% endfor %}
