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.
Syntax
Example
Click the following to display all results:

NaN is a property of this global object. In other words, it is a variable in the environment section. Initial
The 
NaN value is Not-A-Number – the same as the Number.NaN value. For modern users, NaN this property cannot be configured or written. Even if this is not the case, the person avoids being ignored. Using NaN in an appropriate program can be quite rare.
- Could not find
- parsed number (for example, or
parseint ("blabla")number (undefined)) - Mathematical operations that may result in an invalid number (for example,
Math.sqrt (-1)) - The argument operand is often
NaN(for example,7 ** nan) - Unspecified institution(e.g.
0 * Infinite,undefined + undefined) - Any operation that contains a string and is not in addition to an operation (for example,
"foo" and 3)
NaN compare unequal == , (via ! = , === and ! == ) to another value, including another NaN value. Use Number.isNaN () or, optionally, isNaN () , to most clearly determine whether a particular value is NaN . Or do a good self-comparison: NaN and only NaN of course compares unequally to you.
What causes NaN JavaScript?
According to def. NaN is the value returned by operations with undefined exact results. Therefore, in JavaScript, it is not part of the world object, but also a Number: Number object. Nope. It is still a numeric data format, but it is undefined as it is valid numeric Lom.
Note, however, the difference between isNaN () Number and .isNaN () : currently the previous return is true . assuming Currently the value is NaN , otherwise it becomes NaN after being forced to a number during this last meeting true only if the current value is NaN :
For the same reason, using the bigint value results in an error with isNaN () and certainly not with `Number.isNaN ():
What is the meaning of NaN in JavaScript?
NaN has always been the property of Global Article. In other words, it is the only variable on a global scale. The most important NaN value is Not-A-Number, which is the same as the Number value. There are five different types of operations that return NaN: number cannot be parsed (for example, parseInt (“blabla”) or number (undefined))
NaN NaN; ===Number.NaN === NaN;isNaN (NaN);isNaN (number.NaN);Number.isNaN (NaN);ValueIsNaN (v) unite v! == v;WertIsNaN (1);WertIsNaN (NaN);WertIsNaN (number.NaN);

How do you fix NaN errors?
Nan is short for “Not a number” because you are not calling the square function in your cube function, you are looking at its contents. Change the return x 6. Square; with return x * pillow (x); and it should work.
