+// lets understand this keyword
+//In JavaScript, the this keyword refers to the object that is currently executing the function. It is a reference to the context in which the function is called. The value of this depends on how a function is invoked:
+
+
+// const user = {
+//     name:"krish",
+//     age:24,
+//      welcomemsg: function(){
+//         console.log(` hello ${this.name}`);
+//         console.log(this);
+//     }
+// }
+
+// user.welcomemsg();
+// user.name = "Abhi";
+// user.welcomemsg();
+
+// this keyword can;t bs used in function
