tree-sitter-haskell VS tree-sitter-javascript

I want to support indentation with Haskell, but after reading the indent queries page, I still don't know how to go about it. I see the https://github.com/tree-sitter/tree-sitter-haskell project but how do I go about installing/enabling indent queries for Haskell?

HLS works quite well with nvim lsp. I saw someone mentioning there were some updates to treesitter for Haskell. Guess this was the repo https://github.com/tree-sitter/tree-sitter-haskell. Not sure. The neovim treesitter repo doesn't list haskell support yet.

I believe goto_next_test requires support from the tree-sitter parser, specifically tree-sitter-javascript in the case of JS and tree-sitter-typescript in the case of TS.

Here is the tree-sitter grammar of Elisp:

https://github.com/Wilfred/tree-sitter-elisp/blob/main/gramm... (approx. 200 lines)

and here is the grammar of JavaScript:

https://github.com/tree-sitter/tree-sitter-javascript/blob/m... (approx. 1200 lines)

JavaScript evolved into a language of similar complexity as Perl 5 (the corresponding tree sitter syntax table counts almost 2000 lines, currently).

Next, clone the Javascript grammar for tree-sitter from https://github.com/tree-sitter/tree-sitter-javascript and compile it with cc -shared -fPIC -g -O2 -I src src/scanner.c src/parser.c -o ~/.emacs.d/tree-sitter/libtree-sitter-javascript.dylib.

I downloaded the tree-sitter-javascript repo, created a folder for a custom grammar package, and created a basic package.json file, but I have no clue what the Atom page is talking about regarding call_expression, and the addInjectionPoint code. ELI5?
