How to pick a random value from random array

[devarajc]

Hi ,

I want to know about in dummy json how to get an random value from customize array. Let my array would be var color = ["blue" , "red", "green"]

Thanks

Here's a quick example of how to write a custom helper to pick a random item from an array:

var helpers = {
  color: function (options) {
    var colors = ['blue', 'red', 'green'];
    return colors[Math.floor(Math.random() * (colors.length))];
  }
};
var template = '{ "background": {{color}} }';
var result = dummyjson.parse(template, {helpers: helpers});

This is quite a common scenario so I plan to make it a little easier to implement in the next major release version.
