Transforming array to object JavaScript
Suppose we have an array of strings like this −
const arr = [ 'type=A', 'day=45' ];
We are required to write a JavaScript function that takes in one such array. The function should construct an object based on this array. The object should contain a key/value pair for each string in the array.
For any string, the part before '=' becomes the key and the part after it becomes the value.
Example
const arr = [ 'type=A', 'day=45' ]; const arrayToObject = (arr = []) => { const obj = {}; for (let i = 0; i < arr.length; i++) { let currentItem = arr[i].split('='); let key = currentItem[0]; let value = currentItem[1]; obj[key] = value; }; return obj; }; console.log(arrayToObject(arr));
Output
And the output in the console will be −
{ type: 'A', day: '45' }
