As a next step do spend some quality time practicing the operators understand how they differ from each other and also try breaking them. In this tutorial, we covered the JavaScript not equal and the other comparison operators.

Greater than or equal to (>=) - Checks if the value is greater than or equal to the value on the right.

Greater than (>) - Checks if the value on the left is greater than the value on the right.

Strict equal to (=) - Checks is two values are equal and of similar type.

Equal to (=) - Check if two values are equal.

Other Comparison Operators:Īpart from the JavaScript not equal and Strict inequality operators, we have a few other operators that solve different use cases. In the last case, we used the strict inequality operator and it returned true as the values were of different types.

Does not equal sign script code#

Execute the following code to satisfy the condition. For example, we want to exclude ProductID 1 and ProductName Winitor (having ProductID 2). We can specify multiple conditions in a Where clause to exclude the corresponding rows from an output. Do note that in the latter case even though we passed 10 as a string the operator was able to compare both the values. Example 4: Specifying multiple conditions using SQL Not Equal operator. In the second and third cases, it returned a false cause the values are the same. In the first case, it returned true as the values were different. In this case, we are checking how many values in the range C2:C10 are not equal to.

However, the “!=” or Strict inequality operator does not attempt to do so and returns false if the values are unequal or of different types.īoth these operators solve different purposes and hence I would recommend practicing them to facilitate further understanding.Ĭode and Explanation: console.log(5 != 10) The symbol <> in Excel/Google Sheets is equivalent to not equal to.

This operator tries to compare values irrespective of whether they are of different types. This is the exact opposite functionality of the equals sign (), which will output TRUE if the values on either side of it are equal and FALSE if they are not. The JavaScript not equal or inequality operator (!=) checks whether two values are not equal and returns a boolean value. If they are not equal, it will output TRUE, and if they are equal, it will output FALSE. This article is a good starting point for the same, however, we do emphasize more on the JavaScript not equal (!= & !=) operators. Given its vast usage, every developer should understand the functionality of each operator.

Hence these operators are used in decision making or as conditional statements for loops. These operators return a boolean value (true or false) based on the condition.

Table of Contents - JavaScript Not Equal:Ĭomparison operators in programming languages are used to compare two values.

The symbolic representation of Not equal operator in JavaScript is. If the value of two operands are not equal it returns true.
