Change certain vimscript to lua

Answer

Hi, I am somewhat a noob when it comes to lua-script, so excuse me if this question is trivial. I want to change this line:

let g:slime_default_config = {"socket_name": "default", "target_pane": "{last}"}

to lua, but I don't know how. I have checked the learn-to-write-nvim-config-in-lua github, it was totally over my head. Can someone help me? Thank you!! 😇
