why params only support int64? and how to convert go types to params such as string, slice about wazero HOT 1 CLOSED

It's just the basic building block.

If you want to pass complex types in and out of the wasm VM, you have some hoops to jump through. The way Rust's wasm-bindgen does it is make a malloc method in the wasm, so you call malloc(len int64) (ptr int64) and then directly access the VM's memory at ptr and write your stuff, and then call readString(ptr, len int64) or something to tell the wasm to read from the memory you just wrote.

It's really a communication layer that needs to be added by whatever's compiling the wasm.
