Before we analyze the code snippet, let’s try to simplify it by removing the setTimeout.
If we just leave the plain console.log in the loop, then the output is all the values of i from 0 to 4 printed on each iteration of the loop.
However, when the setTimeout is added, the console.log will be executed after the loop has already been processed and the value of i is 5.
As i was declared with var, it has the global scope and the intermediary values aren’t stored in closure around the arrow function () => console.log(i).
ANSWER: the value 5 will be printed on the screen 5 times. Each time on the new line.
