'use strict';; const transaction = id: 1000 reference: "ABC123" amount: 1004 date: "2010-01-01"; // Lock id and reference from modification, with no errors to be thrown.; transactionid = 1001; // This is ignored, even in strict modetransactionreference = "DEF456"; // This is ignored, even in strict mode console; // 1000console; // ABC123
Lock a property on a class
