I am creating an application in which I have a page for creating a customer. for that I have written following code.
customer=new MobileApp.CustomerViewModel(); //for creating new customer
I want to delete this object. how can I perform this ??

Setting customer = null will make this enable for garbage collector, given that there is no other valid reference to that object.

delete customer;
See about delete
delete operator removes a property from an object. As customer is a property of the global object, not a variable, so it can be deleted
Note : customer should be a global one
customer=new MobileApp.CustomerViewModel();
delete customer; // Valid one
var customer1=new MobileApp.CustomerViewModel();
delete customer1; // Not a valid one

This doesn't answer the question, and delete doesn't affect memory: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…
Recursively destroy the object as shown below. Tested with chrome heap snapshot that the javascript objects are getting cleared in memory
function destroy(obj) {
for(var prop in obj){
var property = obj[prop];
if(property != null && typeof(property) == 'object') {
destroy(property);
}
else {
obj[prop] = null;
}
}
}
deletekeyword is NOT for deleting contents from memory, it is only for removing properties from within an object. Read the docs. Note thatdelete x;Will attempt to delete a propertyxthat exists in the global namespace object.
