It Can Do Math Too?

JavaScript wouldn't be much of a programming language if it couldn't do simple math. While there are dozens of complex, built-in math functions, here arerepparttar 105598 basic symbols you'll need to know:

addition + subtraction - multiplication * division / greater than > less than < greater than or equal >= less than or equal <=

What "If" Statements

"If" statements are often used to compare values. Ifrepparttar 105599 statement is true, a set of instructions enclosed in {} executes. Comparisons like this are done usingrepparttar 105600 following symbols:

equals == not equal !=

Inrepparttar 105601 example below, you can see how an "if" statement is used to determine text that displays in an alert window. Copy and pasterepparttar 105602 following script into an HTML page to see it at work.

Notice howrepparttar 105603 instructions for each statement (bothrepparttar 105604 "if" and "else") are enclosed in {}(curly brackets). All curly brackets must have a beginning and ending, just like HTML tags. If a curly bracket is missingrepparttar 105605 JavaScript will return an error, so be sure to proof your code.
