Convert array of string into array of object with different keys JS

If you only have one array containing one set of data there's no need to use map. Destructure the array elements, and then just create a new object using those variables.

const arr = [ '612772d3d8b2b2000482fc3c', '15', '15', 'Basketball', '2021' ];

const [ id, amount, bet, sport, date ] = arr;
const obj = [ { id, amount, bet, sport, date } ];
console.log(obj);

How to convert an Array to Array of objects with same keys in Javascript?

arr.map(function(o) {
   return {
      name: o,
   }
})

    name: value
  };
})

How to convert an array of type String to an array object in javascript

What you have here is a JSON string. You can parse it to get the object / array:

var array = JSON.parse(arrayString)

Edit: I see your JSON string has single quotes. You need to replace all of them with double quotes before parsing:

JSON.parse(arrayString.replace(/'/g, '"'))
