I'm converting a Object in Typescript to a string to store into a database.
formData.survey_data = encodeURI(JSON.stringify(formData.survey_data));
The output works,in the browser but typescript insists I have an error.
Type 'string' is not assignable to type 'any[]'
What does that even mean?

Reset to default 4formData.survey_data = encodeURI(JSON.stringify(formData.survey_data));
Based on the code provided, I would assume that survey_data is type any[]. You are serializing your object and trying to assign it to that property. TypeScript is strongly typed and won't allow you to do that even though JavaScript may be able to handle that scenario. (Because JavaScript isn't strongly typed you can assign any object to any property).
