JavaScript Operators

JavaScript Assignment Operators

Assignment operators are used to assign values to JavaScript variables. Given that x=10 and y=5, the table below explains the assignment operators:

Comparison Operators

Comparison operators are used in logical statements to determine equality or difference between variables or values. Given that x=5, the table below explains the comparison operators:

Operator    Description Example

==     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.
