==     is equal to   x==8 is false

===   is exactly equal to (value and type)   x===5 is true

                   x==="5" is false

!=      is not equal x!=8 is true

>       is greater than      x>8 is false

<       is less than  x<8 is true

>=     is greater than or equal to        x>=8 is false

<=     is less than or equal to   x<=8 is true

 

 

Conditional Operator

 

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

 

Syntax variablename=(condition)?val ue1:value2 Example

greeting=(visitor=="PRES")?"Dear President ":"Dear ";

 

If the variable visitor has the value of "PRES", then the variable greeting will be assigned the value "Dear President " else it will be assigned "Dear".

 

Conditional statements in JavaScript are used to perform different actions based on different conditions.
