How to make array of objects in Twig?

Question

I'm new to TWIG...
Within a TWIG template, I need to create a new array of objects that is a subset of an existing array of objects (products).

So far, I have this:

{% set onlyLimitedAmtProds = [] %}
{% for product in products %}
    {% if product.in_stock_amount < 3 %}
        {% set onlyLimitedAmtProds = onlyLimitedAmtProds|merge(product) %}
    {% endif %} 
{% endfor %}

The above generates an error of:
"The merge filter only works with arrays or hashes; array and object given."

I'm not sure of the syntax to make this work.

You are actually trying to merge array onlyLimitedAmtProds with object product. But merge function works only with two arrays. You need to merge with an array of one element: merge([product]).
