Get an array with non duplicate values from multiple array

Question

I need to go through multiple arrays and create one new array with all the values from the multiple arrays without duplicate, is there any plugins/quick way I can do this?

var x = {
  "12": [3, 4],
  "13": [3],
  "14": [1, 4]
};

The result should look something like this:

[1,3,4];

Answer 1

You can do this using ES6 spread syntax and Object.values method.

var x = {
  "12": [3, 4],
  "13": [3],
  "14": [1, 4]
}

const result = [...new Set([].concat(...Object.values(x)))]
console.log(result)

Solution using Lodash

var x = {
  "12": [3, 4],
  "13": [3],
  "14": [1, 4]
}

const result = _.uniq(_.flatten(_.values(x)))
console.log(result)
