Quadratic Complexity

As you might guess by now-- in a function with quadratic complexity, the output steps increase quadratically with the increase in the inputs. Have a look at the following example:
xxxxxxxxxx
12
function displayAllProducts(items) {
for (let item of items) {
for (let innerItem of items) {
const result = item * innerItem;
console.log(result);
};
}
}
const inputs = [2, 3, 4, 5, 6, 7];
displayAllProducts(inputs);
