A callback function in JavaScript is a type of function that is passed as an argument to another function. This function is then called inside the parent function to complete a routine or an action. In simpler
There are lots of different type conversions described in the spec. One of them isToInteger. JavaScript uses it when a standard function expects an integer argument. Before the use of the passed argument, JavaScript appliesToIntegerto the value of that argument. If the value is NaN, thenToIn...

In JavaScript, asynchronous operations are those that do not interrupt the main thread, letting the program start and carry out other operations while it waits for time-consuming processes, like file I/O or data fetching, to finish. Due to its non-blocking methodology, web applications are guar...
First, heavy computation could choke up Node’s single thread and cause problems for all clients, as incoming requests are blocked until said computation is completed. Second, developers need to be vigilant and prevent exceptions from bubbling up to the core (top) Node.js event loop, as this...
In the above, you can refer to the variablesqlbecause it is only assigned once. If you were to assign to it a second time, it would cause a compilation error. 2.3Method references Since a lambda expression is like an object-less method, wouldn’t be nice if we could refer to existing...
