To get rid of the printfs, we need a way of converting a expr<\/code> to JSON.<\/p>\n
Let’s encapsulate the expression conversion in a new module, dedicated to transforming expressions into JSON representation:<\/p>\n

The new Json<\/code> module will implement two functions. The function expr_to_yojson<\/code> basically maps our expr<\/code> types to Yojson.t<\/code>. The function expr_to_string<\/code> will use the previous function to convert from Yojson.t<\/code> to string<\/code>.<\/p>\n
If eventually we decide to change the way we want to render JSON, like using a more performant library, for example, we refactor this module and there’s no need to update anywhere else — maybe the tests.<\/p>\n
With that, we can remove our messy hand-written print function:<\/p>\n
