What are koa-is-json's main functionalities?

Check if a value is JSON

This feature allows you to check if a given value is a JSON object. The code sample demonstrates how to use the koa-is-json package to verify if a value is JSON and log the result.

const isJSON = require('koa-is-json');

const value = { key: 'value' };

if (isJSON(value)) {
  console.log('The value is a JSON object');
} else {
  console.log('The value is not a JSON object');
}
