What language is in the ".liquid" files?

Question

I had a small task to add a function to a theme made in Shopify. I am good with PHP, but shopify uses .liquid files. I want to know how this works, how this piece of code

{{% if payment.gateway | name %}}

Although they provided documentation, but I want to know how I can work in this language, because I do not have a free version of the paid version, and I want to try this before paying for it. Can someone help me?
