The code that creates the condition for the "if" statement is embedded within an else statement. The else statement will be at the end after the code for the "if" has run. The "if" and the else are one and the same statement - they are just written differently. The code that executes inside the else statement will be a series of if statements, with each one of them causing a different condition to be true.

The basic idea behind both the "if" and "else" is that they create a series of conditions that a JavaScript code must satisfy in order to continue running. JavaScript's if statement is used more often than you might think, although you don't actually need to understand the "if" or the "else" - you just read the Java's bytecode to know what each if statement is doing. Once you get a bit more familiar with Javascript, you can start to learn how to use your Javascript if statement to write some actual JavaScript, not just "if" statements.
