There are 6 types of comparison operator.

1. Greater/less than(>/<)

2. Greater/less than or equal(>=/<=)

3. Equals(==)

4. Not equals(!=)

5. Strict equal(===)

6. Strict not equal(!==)

Greater/less than(>/<)

Greater/less than operator is used to compare the value whether it is greater or less based on that it return true or false

eg-

13>24
false

10<100
true

Greater/less than or equal(>=/<=)

The greater than oe equal to this is new operator that checks whether the value is greater than or equal to another value.

eg-

10>=12
false

10<=10
true

Equals(==)

This is for checking equality whether the value on the left hand side equal to on the right hand side or not.

• it is also known as Double equal
• In double equal implicit type conversion happen.

eg-

0 == 0
true

20 == 22
true 

12=="12"
true(implicit type convesion happen)

Not equal(!=)

Not equal operator is compare the value and based on comparison gives the true or false.

eg-

21 != 21
false

"Hello" == "Hello"(because they are equal)
true

21 != 210
true

Strict Equal(===)

Strict equal only give true if the value of both right hand side and left side are of same type.

• it is also known as triple equal
• In triple equal explicit type conversion happen.

eg-

21 === "21"
false (false because  the value of both right hand side 
and left side are not in same type)

0 === 0
true

Strict Not Equal(!==)

Strict Not Equal only give true if the value of both right hand side and left side are not equal or not of same type.

eg-

2 !== "32"
true
