How to implement properties preprocessing before execution like it is done in Grunt?

问题

Grunt has syntax which is used to set and update configuration properties before task execution.

For example,

config {
  dist: {
     dir: "dir1"
  },
  clean: {
      dirs: [
          '<dist.dir>'
      ]
  }
}

becomes in memory to ...

config {
  dist: {
     dir: "dir1"
  },
  clean: {
      dirs: [
          "dir1"
      ]
  }
}

What npm module is responsible for this? Please, advice me how to implement it in a better way? Thank you!

Template Strings within Grunt come from the Lo-Dash package.
