javascript check if json file is empty

//First of all JSON fle cannot be completely empty, you need to make sure
//it has atleast a pair of double curly braces "{}". Otherwise you will
//get an error.

//import the file system library
const fs = require('fs');

//Then load it into a varibale
var webProjects = JSON.parse(fs.readFileSync('webProjects.json'));

// Then the if statement below can be used to check if it is empty
if(Object.entries(webProjects).length === 0)
