wasm-opt: Apply default optimizations and write to a given file.
$ wasm-opt -O ${input-wasm} -o ${output-wasm}
try on your machine

The command "wasm-opt" is used to optimize a WebAssembly (Wasm) module. Here's a breakdown of each part of the command:

  • "wasm-opt": This is the name of the command-line tool that is being executed.
  • "-O": This flag specifies the level of optimization to be applied. In this case, it is set to "O", which stands for "aggressive optimization". There may be other optimization levels available depending on the tool and its version.
  • "${input-wasm}": This is a placeholder for the input Wasm file. It is typically replaced with the actual path and filename of the Wasm module that needs to be optimized.
  • "-o": This flag indicates that the following argument is the output file. It specifies where the optimized Wasm module will be saved.
  • "${output-wasm}": Similar to the input placeholder, this is a placeholder for the output Wasm file. It is replaced with the desired path and filename for the optimized Wasm module.

So, when you run the command with the appropriate input and output placeholders replaced, it will optimize the input Wasm module and save the optimized version to the specified output file.
