I do not know why this won't work. It is very easy to read and four line of code. 

<script>
/*Why Nothing appears in my browser? I think I am allowed to
 use a method on a property because value.upperCase will work.*/
let num='34534234'
alert(num.length.JSON.parse('2'))
/*Why the second line of code works if the first line of code won't work?*/
h1.classList.add()

.
</script>

Hi, there, first of all JSON.parse() method is going to convert JSON data into a javaScript object, in this case, variable num is a not JSON data. so it will not going to return anything

secondly, length property is going to return the number of character, in this case is number 8. number is not a JSON data JSON.parse will not going to return anything either.
