javascript - split method of array

Question

'1,2,3,4,5'.split(',');
The above code will output ['1','2','3','4','5'] ;
Each value in the array is of string type. Is there any good way to make the values ​​in the split array become number type?

Answer 1

You can only traverse it again after splitting

Answer 2

var number = '1,2,3,5,4,9,8,7'.split(','),
    out = [];
for(var i=0;i<number.length;i++){
    out.push(+number[i])
}
console.log(out)
[1, 2, 3, 5, 4, 9, 8, 7]

Answer 3

const a ='123456';
a.split(' ').map (i => Number(i))

Answer 4

The type of your split ('1,2,3,4,5') is originally a string, just a string composed of numbers. Therefore, it is right for the array formed after split to maintain its original type. Because it is not a numeric type. To change it to number type, just iterate through the array and convert each element.
