Week 23: November 3-7: I knew it!

  Hi!

      Oh! We celebrated the  Intramurals 2014. And on Monday, Sir discussed about the JavaScript 3.
Here are examples...

 Conditional Operator

JavaScript also contains a conditional operator that assigns a value to a variable based on some condition.

 It is ok to use conditional operators like a statement like so?

(x == y) ? alert("yo!") : alert("meh!");

Or is it more correct to use it to assign a value like so?

z = (x == y) ? "yo!" : "meh!";

Logical OR Operator

Logical operators are used to determine the logic between variables or values.

Given that x=6 and y=3, the table below explains the logical operators:

Operator	Description	Example
&&	and	(x < 10 && y > 1) is true
||	or	(x == 5 || y == 5) is false
!	not	!(x == y) is true

Using Parse Float() Function

     The parseFloat() function parses a string and returns a floating point number.

This function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.

Note: Only the first number in the string is returned!

Note: Leading and trailing spaces are allowed.

Note: If the first character cannot be converted to a number, parseFloat() returns NaN.
