Continuation

Continuation of our JS3! :D Here it is...

Javascript provides three methods to convert the premitive data types. They are:

• String
• Numeric
• Boolean

These are also the example of the three methods.

The parseInt() Method - This method is used to get the primitive data type of a certain String. parseXxx() is a static method and can have one argument or two.

The parseFloat() Method - 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.

The eval() Method - The eval() function evaluates or executes an argument.

If the argument is an expression, eval() evaluates the expression. If the argument is one or more JavaScript statements, eval() executes the statements.

Lastly,

The Conditional Operator - The conditional operator (? :) is a ternary operator (it takes three operands). The conditional operator works as follows:

• The first operand is implicitly converted to bool. It is evaluated and all side effects are completed before continuing.
• If the first operand evaluates to true (1), the second operand is evaluated.
• If the first operand evaluates to false (0), the third operand is evaluated.

So that's it. :) Bye.
