The process of converting an object to a string in Typescript

Currently, I am transforming an Object in Typescript into a string for storage in a database.

formData.survey_data = encodeURI(JSON.stringify(formData.survey_data));

The result functions correctly in the browser, however, there is an error being flagged by Typescript.

The message states: 'Type 'string' is not assignable to type 'any[]'

I am confused by what this means. Can someone please explain?

Answer №1

formData.survey_data = JSON.stringify(formData.survey_data);

From the provided snippet of code, it appears that the variable survey_data is being encoded as a URI string. It seems like this variable might be of type any[]. By serializing and assigning the object to this property, you may encounter issues with TypeScript's strong typing system. Although JavaScript could potentially handle this scenario due to its lack of strict typing rules, TypeScript would not allow such assignment without explicit handling for type conversions.
