I can't understand the following code. I do not know which line start first. Please clarify it in simple English. Thanks

You can create functions that provide new types of control flow that aren't available with loops and conditional statements

Example: A function that executes a given function unless a test condition is true.

function unless$($test$,$ then$)\{$

if $(!$test$)$ then$()$;

$\}$

function repeat$($times$,$ body$)\{$

for $($var i $=0$; i $<$ times; i$++)$

body$($i$)$;

$\}$

repeat$(3,$ function$($n$)\{$

unless$($n $\%2,$ function$()\{$

console.log$($n$,"$is even"$)$;

$\})$;

$\})$;

$//0$ is even

$//2$ is even
