In this tutorial, we are going to identify some possible causes that can cause a nan error in javascript, and then I will suggest some possible fixes that you can try to fix the problem. NaN is an error value that means there is no packet. However, JavaScript assumes that a type using NaN is a number. Infinity is literally so big a value that it is not represented by JavaScript numbers. Basically it behaves like mathematical infinity.

Description

The literal NaN without quotes is another value that represents a non-number. Since NaN is often compared to an unequal number and NaN is suggested, it is commonly used to denote an error condition for the corresponding function that should return the corresponding number.

How do I fix NaN error in JavaScript?

Using the isNaN () method: The isNan () method is called to check if the specified number should be NaN or not.Using || Operator: If “number” is incorrect, it will be reset to 0.Using the ternary operator: Here the number is provided by a ternary operator similar to a if NaN is effectively convertible to 0.

Note. Use isNaN () globally to see if a value is a NaN value.
