Convert array of "key-value" pairs into object using javascript

New123 :

I have array of key and value pairs as

let array = [
  "Social Network: 1",
  "Tasks: 1",
  "Calendar: 1",
  "Journal: 1",
  "Business Contact Manager: 2"
];

I want convert this into an object as shown below:

{
  "Social Network": 1,
  "Tasks": 1,
  "Calendar": 1,
  "Journal": 1,
  "Business Contact Manager": 2
}

How can I achieve this?

Mohammad Usman :

You can use .reduce() and .split() to get the desired output:

let array = ["Social Network: 1", "Tasks: 1", "Calendar: 1", "Journal: 1", "Business Contact Manager: 2"];

let result = array.reduce((r, c) => {
  let [k, v] = c.split(":");
  r[k] = Number(v);
  return r;
}, {});

console.log(result);
