I want to replace all fields with null values so that it does not proceed with the model further. Now when I am creating a replacer function and passing the model. I am getting a circular reference issue. Is there any better way to do this so that I do not get the error
const replacer = function (k, v) {
if (v === '') {
return undefined
}
return v
}
return JSON.parse(JSON.stringify(this.getData(), replacer))
I'm not sure that I fully got your goal, but if you have an array of data, and that you want to replace each empty string item by undefined you could simply do
const example_data = ["hello", "", "", "world", "!", ""];
const empty_to_undefined = example_data.map(item => item === "" ? undefined : item);
console.log(empty_to_undefined)
