TypeError: toFixed is not a function in JavaScript

Sometimes, when we use the toFixed() method, we may see the error TypeError: toFixed is not a function. This is because the toFixed() method is called on a value that is not a number.

Solution #

To solve that problem, convert the value to number using the Number() method.

<script>
  const myString = '12.8798';
  const newNumber = Number(myString).toFixed(2);
  console.log(newNumber)
</script>

Here is an example of how this error occurs.

<script>
  const myString = '12.8798';
  console.log(myString.toFixed(2));
</script>

To fix this error, first we can convert the value to a number before calling the toFixed() method.

However, do you know how we can check whether a variable is a number or a string?

That's easy. we can use the typeof operator to check. Try the below example.

Example : uses of typeof operator. #
<script> 
  const num = '12345';

  console.log("'12345' is a " + typeof num)
  console.log("myVar is a " + typeof myVar)
  console.log("9 is a " + typeof 9)
  console.log(" [5,6,7] is a " + typeof [5,6,7])
</script>

Now come to the topic. To convert a string to a number, we can use the Number() method. E.g.

Example : fix the error toFixed is not a function. #
<script>
 const myString = '12.8798';
 const result = Number(myString).toFixed(2);
 console.log(result)
</script>

Conclusion #

  1. The parseFloat() method parses a value as a string and returns the first number.
    If it encounters an invalid character, it returns the number represented up to that point, ignoring the invalid character and all characters that follow it.
    <script>
    const myString = '12.8h798';
    const newNumber = parseFloat(myString).toFixed(2);
    console.log(newNumber)
    </script>
