![]() ![]() In the following sections, I’ll delve deeper into the not equal operator, comparing it with other JavaScript operators and explaining common mistakes to avoid. By knowing how to use the not equal operator correctly, you can write code that is more efficient, readable, and bug-free. For instance, you might use the not equal operator to validate user input in a form or to check if a value exists in an array. It allows you to compare different types of values and execute code based on the result. Understanding the not equal operator is crucial for writing effective JavaScript code. However, if you compare the number 5 with the string “10”, the result will be “true” since the values are not equal. For example, if you compare the number 5 with the string “5” using the not equal operator, the result will be “false” since both values are considered equal. ![]() It compares two values and returns “true” if they are not equal and “false” if they are equal.
