# Comparators Lets now focus on the conditional part: ~~~ if (country === "France") { ... } ~~~ The conditional part is the variable `country` followed by the three equal signs (`===`). Three equal signs tests if the variable `country` has both the correct value (`France`) and also the correct type (`String`). You can test conditions with double equal signs, too, however a conditional such as `if (x == 5)` would then return true for both `var x = 5;` and `var x = &quot;5&quot;;`. Depending on what your program is doing, this could make quite a difference. It is highly recommended as a best practice that you always compare equality with three equal signs (`===` and `!==`) instead of two (`==` and `!=`). Other conditional test: - `x > a`: is x bigger than a? - `x < a`: is x less than a? - `x <= a`: is x less than or equal to a? - `x >=a`: is x greater than or equal to a? - `x != a`: is x not a? - `x`: does x exist? Exercise Add a condition to change the value of `a` to the number 10 if `x` is bigger than 5. ~~~ var x = 6; var a = 0; ~~~ ### Logical Comparison In order to avoid the if-else hassle, simple logical comparisons can be utilised. ~~~ var topper = (marks > 85) ? "YES" : "NO"; ~~~ In the above example, `?` is a logical operator. The code says that if the value of marks is greater than 85 i.e. `marks &gt; 85` , then `topper = YES` ; otherwise `topper = NO` . Basically, if the comparison condition proves true, the first argument is accessed and if the comparison condition is false , the second argument is accessed.
