turning array's items from strings to numbers

I would like to turn the items stored in the numbersToSum array from strings to numbers, but I don't know how or where I should apply the parseInt

let numbersToSum = [];

displayField.value = '';

//digit numbers in display

digit.addEventListener('click', (e) => { if(e.target.className === 'number-btn'){ displayField.value += e.target.innerHTML; }

//storing numbers in the array

if(e.target.className === 'sum-btn'){ numbersToSum.push(displayField.value); displayField.value = ''; }})

If you want the array to contain only numbers, you'd want to convert before (or as) you push the values into the array:

numbersToSum.push(parseInt(displayField.value));
