Multiply numeric property values by 2
importance: 3
Create a function multiplyNumeric(obj) that multiplies all numeric property values of obj by 2.
For instance:
// before the call
let menu = {
width: 200,
height: 300,
title: "My menu"
};
multiplyNumeric(menu);
// after the call
menu = {
width: 400,
height: 600,
title: "My menu"
};Please note that multiplyNumeric does not need to return anything. It should modify the object in-place.
P.S. Use typeof to check for a number here.
function multiplyNumeric(obj) {
for (let key in obj) {
if (typeof obj[key] == 'number') {
obj[key] *= 2;
}
}
}
