JavaScript Comparison Operators

In this post, we will be learning about JavaScript's comparison operators.

Comparisons Operators

Comparison operators are used for determining whether a literal equal or differs from another literal.

Two equal signs ("==") will check only the value of literals, while three equal signs ("===") checks whether they are both the same value and the same type. For example, if x equals 6, then the operators below will return the value listed in the return column.

Of particular note is that for two equal signs, 6 and "6"(a string) are equal, while for three equal signs they are not.

How Comparison Operators Can be Used

Comparisons are used to determine whether a variable matches a certain condition.

If the condition matches (the condition is true), we execute some block of code. Otherwise, (the condition is false), we execute another block of code.

JavaScript Code

if(age<18)
{
document.write("Sorry, you are too young");
}
else
{
document.write("Congratulation, you are old enough!");
}

Logical Operator

We use logical operators to specify relations between conditions.

For example, we can see whether a variable meets condition A and condition B or we can see whether a variable meets condition A or condition B.

Comparing Different Types

The above are some examples of types being compared.
