Gulp loop from json file

path.json

{
  "plguin_a_name": {
    "css": {
      "src/plugin_a/1.css": "dist/plugin_a/1.css",
      "src/plugin_a/2.css": "dist/plugin_a/2.css"
    },
    "js": {
      "src/plugin_a/1.js": "dist/plugin_a/1.js",
      "src/plugin_a/2.js": "dist/plugin_a/2.js"
    }
  },
  "plugin_b_name": {
    "css": {
      "src/plugin_b/1.css": "dist/plugin_b/1.css",
      "src/plugin_b/2.css": "dist/plugin_b/2.css"
    },
    "js": {
      "src/plugin_b/1.js": "dist/plugin_b/1.js",
      "src/plugin_b/2.js": "dist/plugin_b/2.js"
    }
  }
}

How can loop from this json file in gulp to copy each plugin from src to dist with a return?

I would like to hae two task to loop only the css/js or loop all object inside "plugin_x_name".

Is this function need some plugin?
