Hey, what is comparison? Y'all know that comparison is the distinction between two things, vary the ups and downs. Likewise, the comparison operator in javascript is the same, which distinguish / compare between the variables or values.
So say if we assign a value to a variable of name x.
1) == (Equal to)
This operator returns the equality of the logical condition of a variable. Let us see it in action with the if-else statement.
x = 100;
if(x == 100){
console.log("It's equal")
}else{
console.log("Not equal")
}Output: It's equal
2) != (Not Equal to)
This operator gives us the not equal comparison of the variable we give as the condition.
x = 120;
if(x != 100){
console.log("It's equal")
}else{
console.log("Not equal")
}Output: Not equal
3) === (Strict Equal To)
When we use this, the given condition should be strictly equal to the variable value and of the same type.
x = 100;
if(x === '100'){
console.log("It's equal")
}else{
console.log("Not equal")
}Output: Not equal
Because we declared x as integer type and not as a string since it has to be equal in type too, here 100 is not equal to '100'
4) !== (Strict Not Equal To)
This operator is satisfied when the operand / value of the variable is equal, but the type is different or not equal at all.
x = 100;
if(x !== '100'){
console.log("if block executed")
}else{
console.log("else block executed")
}Output: if block executed
So here, it doesn't care about the type, meaning that this operator needs at least some match to be satisfied.
5) > (Greater Than)
If the value / operand of x is greater than the assigned value, then the condition is satisfied as true.
x = 100;
if(x > 100){
console.log("value is greater than 100")
}else{
console.log("value is less than or equal to 100")
}Output: value is less than or equal to 100
6) >= (Greater Than Or Equal To)
When the operand / value of x is greater or equal to the value assigned, this satisfies.
x = 100;
if(x >= 100){
console.log("value is greater than or equal to 100")
}else{
console.log("value is less than 100")
}Output: value is greater than or equal to 100
7) < (Less Than)
Quite the opposite of > this operator is satisfied when the assigned value is less or it'' returns false.
x = 100;
if(x < 100){
console.log("value is less than 100")
}else{
console.log("value is greater than or equal to 100")
}Output: value is greater than or equal to 100
8) <= (Less Than Or Equal To)
If the operand/value is lesser or equal to the assigned value, this satisfies.
x = 100;
if(x <=100 ){
console.log("value is less than or equal to 100")
}else{
console.log("value is greater than 100")
}Output: value is less than or equal to 100
