Relational Operators test or define the kind of relationship between two entities. Relational operators return a Boolean value, i.e., true/ false.
Assume the value of A is 10 and B is 20.
| Operator | Description | Example |
|---|---|---|
| > | Greater than | (A > B) is False |
| < | Lesser than | (A < B) is True |
| >= | Greater than or equal to | (A >= B) is False |
| <= | Lesser than or equal to | (A <= B) is True |
| == | Equality | (A == B) is True |
| != | Not equal | (A != B) is True |
Example
var num1:number = 5;
var num2:number = 9;
console.log("Value of num1: "+num1);
console.log("Value of num2 :"+num2);
var res = num1>num2
console.log("num1 greater than num2: "+res)
res = num1<num2
console.log("num1 lesser than num2: "+res)
res = num1>=num2
console.log("num1 greater than or equal to num2: "+res)
res = num1<=num2
console.log("num1 lesser than or equal to num2: "+res)
res = num1==num2
console.log("num1 is equal to num2: "+res)
res = num1!=num2
console.log("num1 is not equal to num2: "+res)
The transpiled JS version of the above code −
var num1 = 5;
var num2 = 9;
console.log("Value of num1: " + num1);
console.log("Value of num2 :" + num2);
var res = num1 > num2;
console.log("num1 greater than num2: " + res);
res = num1 < num2;
console.log("num1 lesser than num2: " + res);
res = num1 >= num2;
console.log("num1 greater than or equal to num2: " + res);
res = num1 <= num2;
console.log("num1 lesser than or equal to num2: " + res);
res = num1 == num2;
console.log("num1 is equal to num2: " + res);
res = num1 != num2;
console.log("num1 not equal to num2: " + res);
It will produce the following output −
Value of num1: 5 Value of num2 :9 num1 greater than num2: false num1 lesser than num2: true num1 greater than or equal to num2: false num1 lesser than or equal to num2: true 14 num1 is equal to num2: false 16 num1 not equal to num2: true
