Using alert

Question

From the code bit attached, I noticed that alert would always execute first irrespective of it's position in the algorithm.
Perhaps I'm still missing something, can someone please shed more light on this?

Answer 1

no it wont, try this

let calc = 5*30/2.3*39;
alert(calc);

if alert fired first, it wont have a chance to show the result of calc. it still wait until previous instruction to finished
