I am learning Javascript, and I am trying to go over everything I have learned so far. I am trying to figure out how to get a message back like an alert box when using the return statement. alert(Example(2,3)); works, also making a gobal variable like this works. var sum = Example(2,3); alert(sum);. But I bet there are better ways then I can think of.
function Example(x, y) {
if (x * y === 108) {
return true;
} else {
return false;
}
}
Example(2, 3);
Your function can be a lot simpler. Just return the boolean you get from the comparison:
function example(x, y) {
return (x * y === 108);
}
As for how to make the alert box, I'd recommend not using alert boxes at all.
console.log or similar.Alerts are highly annoying and prevent interaction with the page.
If for some reason you have to use an alert (for example, you're forced to debug on a system with no developer tools) then this will work just fine:
alert(example(2,3));
Have it this way, :)
function Example(x, y) {
return x * y === 108;
}
Example(2, 3);
console.log, set breakpoints, etc.
sumwhen its value is either true or false.
