I made it that way:

if I have:

var jsonArg1 = new Object();
    jsonArg1.name = 'calc this';
    jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
    jsonArg2.name = 'calc this again';
    jsonArg2.value = 2.73;

var pluginArrayArg = new Array();
    pluginArrayArg.push(jsonArg1);
    pluginArrayArg.push(jsonArg2);

to convert pluginArrayArg (which is pure javascript array) into JSON array:

var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

Converting an array to a JSON object with custom key names

With and without Babel: https://jsfiddle.net/srxs4mcw/ The Babel summary: var arr = ["first", "second", "third", "fourth"]; var keys = ['one', 'two', 'three', 'four']; const newArr2 = arr.reduce((acc, val, i) => ({ ...acc, [keys[i]]: val }), {}); You reduce your array starting with an empty object. Each iteration spreads the accumulated object and adds the new array item to it. This one requires Babel to transpile your code. In my jsfiddle you'll also see a vanilla JS solution which is basically the same thing. More on reddit.com

r/webdev on Reddit: Converting an array to a JSON object with custom key names

April 21, 2017 -

I have an array of strings that I'd like to convert to a JSON object with custom keys.

//Original array
var arr = ["first", "second", "third", "fourth"];

//Preferred JSON format with custom key names
{
  "entries": [
  {
  "one": "first",
  "two": "second",
  "three": "third",
  "four": "fourth"
  }
 ]
}

Struggling to figure this out. Any help would be greatly appreciated.

With and without Babel: https://jsfiddle.net/srxs4mcw/ The Babel summary: var arr = ["first", "second", "third", "fourth"]; var keys = ['one', 'two', 'three', 'four']; const newArr2 = arr.reduce((acc, val, i) => ({ ...acc, [keys[i]]: val }), {}); You reduce your array starting with an empty object. Each iteration spreads the accumulated object and adds the new array item to it. This one requires Babel to transpile your code. In my jsfiddle you'll also see a vanilla JS solution which is basically the same thing.

Obviously, you need a function that emits the custom keynames or an array containing it, then you can use the following: var arr = ["first", "second", "third", "fourth"], keys = ["one", "two", "three", "four"]; // could also be a function function arr2obj(arr, keys) { var obj = {} for (var i = 0, l = arr.length; i < l; i++) { obj[typeof keys === 'function' ? keys(i) : keys[i] || i] = arr[i]; } return obj; }
