How to make json object ready only

Question

Say I have a JSON object var student = {name: 'Anil', Age: 27}; student.Age = 30; // I want to restrict this code. Please help me to understand, how can we make JSON object read only type.

HiAnil, For making object as read-only you can use var obj={pasta: "spaghetti" ,length:10}; Object.freeze(obj); For making specific property as read-onlyyou can use Object.defineProperty(obj, "propertname" ,{configurable: false ,writable: false }); If the above solution is helpful then, accept the answer.

Hi anil Kumar, you can check like Object . keys ( obj ). length === 0 && obj . constructor === Object another way function isEmpty(obj) { for (var x in obj) { if (obj.hasOwnProperty(x)) return false; } return true; }
