if you make a two dimensional array can you name the children of the array?

if you keep up the score of students var student=[ ['Urlie',10,40,50], ['Jasper', 60, 1,1] ];

but if you want to add a score to Jasper you have to remember that is is on the second place of the array. Can you also name the array like the mother is named student?

The elements inside an array (at any nesting level) are always accessed by index.

For components to have names you would need a different kind of structure, for example a JavaScript object.
