Why is the computed property throwing an error?

Question

Vue.js

computed: {
    replaceDotOnComma(value) {
      if (!value) return '';
      return (''+ value).replace('.',',');
    }

I wanted to make a simple property that returns a value by slightly changing the input value ( 33.4 => '33,4' ).
Why does it say that replaceDotOnComma is not a function and how do I do that?
The computer property can take an input parameter. I don't seem to need a setter, because I don't write anything anywhere.

Answer 1

replaceDotOnComma is not a function. And cannot be called as a function
