Converting string to array in es6

Question

How do i convert the following string input name: xyz friend: abc mobile: 123 into an array separating it as something like this [{key:"name", value:"xyz"}]

I have tried this code for splitting

let friend1 = 
'name:xyz 
friend:abc 
mobile_no:123'
let Array=friend1.split(" ");
console.log(Array)`

need help with the key and value part.

Why don't you use a proper data structure like JSON instead? — str

Try this:

To remove colliding colon + whitespace pairs :, I replace them with ####
Then split the array on the rest of whitespaces
For each split, being in this case name####xyz, friend####abc and mobile####123, split them on #### and construct desired object

let string = "name: xyz friend: abc mobile: 123";
let array  = string
  .replace(/:\s/g, '####')
  .split(' ')
  .map(pair => {

    let split = pair.split('####');
    return { key: split[0], value: split[1] };

  });
  
console.log(array)

But you don't have to make it that easy. How would you break JSON.parse?

Define "break". In that case, for me, JSON.parse("name: xyz friend: abc mobile: 123") is "broken". Nvm. I can only assume it is going to be used to parse some chunks of data stored locally, and not in production code. And as you can see, it helped.

Passing invalid inputs to a function which then by specification fails to parse it is not the same as breaking it. Breaking in this context means that with a given input, the function produces something that was not specified. e.g. name: x y.

If the input itself is an array, then this will do the object(dictionary) conversion

var targetDictionary = {};
var string = ["name: xyz", "friend: abc", "mobile: 123"];
for (var i = 0; i < string.length; i++) {
    var split = string[i].split(':');
    targetDictionary[split[0]] = split[1];
}
