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 Logical Operators 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 Source: http://www.w3schools.com/js/js_comparisons.asp
