so if it is not found it will be -1, and if it is found it will be > (greater than or equal to) 0. This is because 0 is an index in the object. The true block of the if condition executes when the condition is not met (when num1 is not equal to num2), and if they match, then the false block is executed.Īs both the variables have different values, the true block of the condition executes. If it is not found, just for safety purposes it returns -1. The variable is on the right side of the operator. Comparison Operators equal value and equal type, x 5 equal value and equal type x 5 not equal, x 8 not equal value or not equal. In the condition, write num1 != num2 where the variable on the left side of the operator is compared. If you cant find the not equal sign on your keyboard, you can copy it using the button above. The not equal sign takes the form of the equal sign with a slash through it.

For example, 0 is not equal to 1, which we express as 1 0. We create an if condition to check if the variables match or not. The not equal sign is used to indicate inequality, when two things are not equal to one another. Here, num1 contains the value 123, and the num2 variable has 321. The program has two int variables, num1 and num2.

The most basic way to use the not equals operator is to check for equality between two variables. We compare two primitive values with the help of an equality operator. In JavaScript, comparing primitive values is relatively easy as compared to objects. We can also use ! with the equals() method to check the non-equality of the data. To check if two objects are equal in JavaScript: Use JSON.stringify () Using lodash Library’s isEqual () function. Otherwise JavaScript attempts to convert non-numeric types to numeric values: Boolean values true and false are. If both values are strings, they are compared as strings, based on the values of the Unicode code points they contain.

This article shows how to use the != operator that we also call the not equals operator. First, objects are converted to primitives using Symbol.toPrimitive with the hint parameter being 'number'.
