Object.values() in jQuery

The prototypeJS library has a method Object.values() which returns an array of values in an object.

EG:

 var myObj = {
   "key1" : "val1"
   "key2" : "val2"
 }
 Object.values(myObj) //returns ["val1", "val2"]

is there a jQuery method that does the same thing?

Solution

  • Using ES6, you can do the following:

    Object.values = x =>
        Object.keys(x).reduce((y, z) =>
            y.push(x[z]) && y, []);

    This simply returns an array containing the object's values. No need for JQuery, _ or anything else.

    note: Object.values() is currently in draft for ES7

    Using babel, installing

    • babel-preset-es2017
    • babel-plugin-transform-runtime

    gives support for Object.values/Object.entries as well as other ES2017 functionality.

    As per recommendation by the modules, configure the .babelrc file with the following:

    {
  "plugins": ["transform-runtime"],
  "presets": ["es2017"]
}
