I did this recently with both lua (luaparse) and javascript (babel), and this is a fundamental tool to have in your toolbox once working with large codebases. Javascript has great tooling for this (see AST explorer and all the different libs it supports).

Before the 1.0 promise, Go used "go fix" to automatically update old code, and the standard library even has tools to manipulate an AST.

The linux kernel uses coccinelle for C code, which goes one step further, and lets you write "semantic patches", which is a DSL to do this in a compact way and without having to write code.
