How to return a boolean value from react native function?
906
The render method returns a description of what the DOM should look like, and then React efficiently updates the real DOM to match." Render is that what exactly you want to trigger multiple times. Return is that which u want to Display.
Use named exports to export a component in React, e.g. export function Button() {} . The exported component can be imported by using a named import as import {Button} from './another-file. js' . You can use as many named exports as necessary in a file.
it can be accomplish like this:
export function isJson(str) {
try {
JSON.parse(str);
} catch (e) {
return false;
}
return true;
}
This function checks whether provided value is valid JSON or not.
