I can add more arrays even if I mention the number of arrays in my code

Question

var courses = new Array(3);
courses[0] = "HTML";
courses[1] = "CSS";
courses[2] = "JS";
courses[3] = "Swift";
courses[4] = "Java";

document.write(courses[4]);

My output is:
Java

Why?
It should not store more than 3 arrays.

Answer 1

Because declaring an array does not require you to state what is the length of the array. Declaring an array is simply var courses = []
