Question

Javascript argparse package allows to enable -v, --version option by default: Javascript argparse package 默认允许启用-v, --version选项：

const parser = new ArgumentParser({
  version: "0.0.1",
  ...

I can comment out the version attribute, and enter something like this:我可以注释掉version属性，然后输入如下内容：

parser.addArgument(["-V", "--version"], {
