JAVASCRIPT - HOW TO Easily Create or Declare a Blank Array and How to Fill the New Array by Adding New Items to the Array Later

To declare an empty of blank array in Javascript ...

let arrnew = []; OR const arrnew = [];

If you want to create an array that is NOT empty and contains elements, each element of the array must be comma separated ...

let arrnew = ['element1', 'element2', 'element 3']; OR const arrnew = ['element1', 'element2', 'element 3'];

To fill the new blank array with new elements is accomplished via the Javascript PUSH method ...

arrnew.push('whatever you want to add to the new array');
