Lodash _.defer


The lodash _.defer method is a utility function that schedules the execution of a function deferred to the end of the current event loop iteration. This method is simply a wrapper for the native setTimeout function with a delay of 0 milliseconds.

Here is an example of using the _.defer method:

_.defer(function() {
   // This function will be executed after the current event loop iteration
   console.log('Deferred function executed');

The _.defer method is useful when you need to delay the execution of a function until after the current event loop iteration. This can be helpful when you are performing computationally expensive operations that may block the event loop and cause a delay in rendering the user interface.

One important thing to keep in mind when using the _.defer method is that it does not guarantee that the function will be executed immediately after the current event loop iteration. Instead, it simply ensures that the function will be scheduled to run as soon as possible.

In addition to accepting a function as its first argument, the _.defer method can also accept additional arguments to be passed to the deferred function:

_.defer(function(arg1, arg2) {
   // This function will be executed with the provided arguments
   console.log(arg1, arg2);
}, 'Hello', 'world');

Overall, the _.defer method is a useful utility function for scheduling function execution at the end of the current event loop iteration in order to avoid blocking the user interface.
