Hi Friends 👋,

Welcome To Infinitbility! ❤️

To convert an array to a string in react native, we can use the toString() method to convert an array to a string but if want to convert an array of objects into a string you have to use the JSON.stringify() method else it will show something like "[object Object]".

Like the following example, we can convert array to string useing toString() and JSON.stringify() methods.

["hello", "shani"].toString(); // 'hello,shani'
JSON.stringify([{greeting: "hello"}]); // '[{"greeting":"hello"}]'
