A function with no parameters that prints how many times it’s
|
||
been called. Hint: define a variable outside of the function to
|
||
keep track of the number of calls, like we did in the “Side
|
||
Effects” section on page 77.

<html><body><script>
|

let a = 0
|

let b = 0
|
||
let c = 0
|
||
|
||
function calledcallback (){a++;console.log(`calledcallback calls: ${a}`)}
|
||
|
||
callback = function () {b++;console.log(`callback calls: ${b}`)}
|
||
|
||
cb = () => {c++;console.log(`cb calls: ${c}`)}
|
||
|
||
calledcallback()
|

callback()
|

cb()
