An empty string converts to 0. In this Knowledge bit, we will discuss more Equality and Inequality Operators in Javascript. The Overflow Blog So just like equality, there is also two way to determine inequality in JavaScript:Just like equality, inequality (!=) will perform type conversion first and then compare the value of the operand.

In this article we’ll learn more about different types of comparisons, how JavaScript makes them, including important peculiarities. yield 1. When comparing two strings, "2" will be greater than "12", because (alphabetically) 1 is less … B. In maths the notation is ≠, but in JavaScript it’s written as a != b. Three most accurate ways to compare strings correctly in JavaScript. While using this site, you agree to have read and accepted our It means that the following expression returns true.

I m trying the same code that we used in double equality example but with three equal sign.So here you can notice in the output, we have got ‘true’ in the result when we compare same value type variable, and we got ‘false’ in output when we compare a variable A whose value is integer 30 to string 30, it is because strict equality operator compares value type too.We use inequality operator to determine the value is equal or not, if not it will return ‘true’. We used these operators to compare two values and evaluate the result in a Boolean value that is true or false.We perform equality operation in JavaScript to determine whether our values are equal or not. If we write A != 49  then we got true, it is because A real value is 50.You can also notice there if we comparing integer 50 to string 50 then we got true in return which means they both values are not equal. 10 + 20; logical not: Logical operators are fully described in the JS Comparisons chapter. The final else is optional.

We will demonstrate with examples that where and how you can use these operators in your program.There are two different way to check equality and inequality in JavaScript.
