How can I multiply an array elements between another array?

I want to do it with the forEach loop but I can’t do it, what I want to do is the following

For example i have the first array:

let numbersA = [4,5,6,7,8];

Then i have the last array:

let numbersB = [2,3,4,5,6];

The expected output:

4 * 2 = 8

4*3 = 12

4 * 4 = 16

4 * 5 = 20

4 * 6 = 24

and now comes the second multiplication of the first array of the second number:

5 * 2 = 10

5 * 3 = 15

5 * 4 = 20

5 * 5 = 25

5 * 6 = 30

How can I get this result, I want to do it with the forEach loop, using arrow functions but I got stuck

Answer

You could use Template Literals to print out the equation:

let numbersA = [4, 5, 6, 7, 8];
let numbersB = [2, 3, 4, 5, 6];
numbersA.forEach(a => {
    numbersB.forEach(b => console.log(`${a} * ${b} = ${a * b}`));
});
