F11 and F9 key in google chrome debugger (javascript). Who cares?

Question

JavaScript

Can you please describe how the F11 (Step into next function call) key and the F9 (Step) key work in the Google Chrome debugger when debugging JS code. And what is the difference between them?

Answer 1

for(let i=0; i<5; i++) {
 //
}
foo()

F11 will jump directly to foo
F9 will loop through each iteration of the loop
