Replace Arrays and Const by getElementById() method ?

[bobkuspe]

Dear all,

Could someone possibly help me figure out how to use the getElementById() method to replace arrays or a variable like Const?

Two examples below:

let arr = [
          ['Team', 'Number of Championships'],
          ['Real Madrid',    66],
          ['Juventus',     37],
          ['Liverpool', 28],
          ['Bayern Munich', 48],
          ['Barcelona',  34]
              ];

and/or

const xValues = [50,60,70,80,90,100,110,120,130,140,150];
const yValues = [7,8,8,9,9,9,10,11,14,14,15];
