"Lua arrays are 1 based. This checks for array access of element 0" - what does this mean?

Question

phpstorm

id = {}
id[0] = "value

"

Answer 1

in lua, an array can have any index, even negative.
but it's customary to start at 1, and many libraries expect this.
in particular, the lua plugin for the idea highlights this as a possible error.
