I just kinda wonder why when you're in a browser or node, you wouldn't just do

const json = {...};
json.friends.filter(f => f.age >= 18);

why learn another language when you already literally got the language to process JavaScript Object Notation right there.

100% agreed. It's just a learning/hobby project, to know more about parsers, and how languages work. Some of the features like Wildcard, Multiple key selection/omission comes handy, and might add more features like that.
