why export default not accepting in const

Uncovered part to javascript 1

const is a javascript keyword for decalring variable,
const a = 3
you can declare multiple vatiable in const like

const a = 4;
      b = 9;

This work well but when you used export and default javascript does not support export and default together.

If you want to assign export in const you need to do the fellowing.

export const = [
name: 'jim',
work: 'FBI'
]

Bonus: when you writing json last value and array should not end with ,.

If you want to use export and default in javascript means then you should used

function sum(a, b) {
return a + b;
}

javascript throw error when you write the export default in const.
