                                    fs.readFile(filePath, function (error, content) {
    var data = JSON.parse(content);
    console.log(data.collection.length);
});

                                    const fs = require('fs');

let rawdata = fs.readFileSync('student.json');
let student = JSON.parse(rawdata);

}
