JavaScript Math.random()

Math.random() returns a random number between 0 (included) and 1 (excluded):

0.4391436681647767

JavaScript "this"

This example demonstrate that in a regular function, the "this" keyword represents different objects depending on how the function was called.

Click the button to execute the "hello" function again, and you will see that this time "this" represents the button object.
