Conditional and logical operators
Operator  Type  Description 

>  Conditional  Evaluates whether the value on the left is greater than the value on the right 
<  Conditional  Evaluates whether the value on the right is grater than the value on the left 
>=, <=  Conditional  Evaluates the same as > or < bur with the additional logic that the values can also be equal 
!=  Conditional  Evaluates whether the values aren't equal 
==  Conditional  Evaluates whether the values are qual independent of the underlying data type 
===  Conditional  Evaluates whether the values are equal both in value and underlying data type 
&&  Logical  The AND logical operator, in which the expressions on both sides must evaluate to true 
  Logical  The OR logical operator, in which at least one expression on either side must evaluate to true 
We will use logical operators to combine conditional operators.
Example:
if(age >= 12) { if(age <= 65) { // logic goes here } }
In the above example first age >= 12 will be evaluated, if it is true then only age <= 65 is evaluated. So, we can combine these two statements into one statement by using Logical operators.
if(age >= 12 && age <= 65) { // logic goes here }
