How to convert javascript array to object

Question

I have an array const arr = ['boy', '2', 'girl', '25', 'dog', '6'] and I want to convert it to and object so it will be come newCreatedObject = {'boy': '2', 'girl': '25', 'dog': '6'} .

Here is what i have tried:

const newCreatedObject = arr.reduce((acc, cur, i, arr) => {
      return {...acc, [cur]: arr[i + 1]};
    }, {})

This is what I get {'6': undefined, '25': 'dog', '2': 'girl', 'boy': '2', 'girl': '25', 'dog': '6'}

the result I want is coming at the later of the object

Answer 1

You need to take only each second element for the result.

 const array = ['boy', '2', 'girl', '25', 'dog', '6'], object = array.reduce( (acc, cur, i, arr) => i % 2 ? { ...acc, [arr[i - 1]]: cur } : acc, {} ); console.log(object);
