1. You’re a tech-savvy person and stay connected with technology. 

First, smart watches do not add a huge value at this stage. It’s pretty expensive compared to what features they offer.

Your co-workers have it and your company plans on offering services, products, hardware, applications related to wearable device. It’s definitely a cool experience.

Smart watches are only going to be better with the same price as to what they offer today. So don’t rush if you don’t have to!

The continue statement breaks only one iteration in the current loop if a defined condition occurs. and it continues with the next iteration in the loop.

The break statement breaks out of the loop. And it lets the code continue executing after the loop.

(7) What is the difference between windows.onload and onDocumentReady?

The onload event does not fire until the last element of the page is loaded including CSS and images etc. There could be a huge delay before onload code on the page is executed.
onDocumentReady will be able to execute code as long as DOM has been is built; without waiting for the elements to be loaded, such as images. That means there will be a faster code execution.

 

 

(8) what is a race condition?

When execution of a certain method or an event call is critically dependent on an another method or event; and if the sequence is not maintained, race condition occurs. As an example; you’re loading an external Javascript on your page and then calling a function from that external JS. Now at the run time if the external JS is not loaded for any reason and your function is already called and looking for that code execution, it’s not going to be executed. This situation is called race condition.

(1) What is event bubbling and capturing in JavaScript?

Event bubbling is series of events when : An event is triggered on the inner most element first and then it triggers on the parent elements in nested order.

DOM elements could be nested inside each other. The handler of the parent works even if you click on it’s child. Event bubbling can make this happen.

Event Capturing is the opposite of bubbling where the event is triggered on the outer most element and then it triggers the inner children in nested order.

I read Jon Duckett’s JavaScript and JQuery: Interactive Front-End Web Development which inspired me writing this post. I’d greatly recommend you reading the book in your spare time. It’s available Amazon.

(2) What is a closure in JavaScript?

JavaScript allows you to declare a function within another function, and the local variables still can be accessible even after returning from the function you called.

In other words, a closure is the local variables for a function which is kept alive after the function has returned.

An example :

function goodMorning(name) {
var text = ‘Good Morning ‘ + name; // local variable
var goodMorningAlert = function() { alert(text); }
return sayAlert;
}

var goodMorningAlert2 = goodMorning(‘Bob’);
goodMorningAlert2();

In the example above, when goodMorningAlert2() will be executed, you will see output as an alert with “Good Morning Bob”.

In short, in JavaScript, if you use the function keyword inside another function, you are creating a closure.

(3) What is a callback function in JavaScript?
(4) What are various methods you’d use to embed JavaScript onto a webpage?
(5) What is the difference between GET and POST methods in HTML form?

When you use a GET method, key and values will be appended at the end of the URL as a query string. GET method is not recommended to use when you are passing sensitive data over the internet.

While sending data, the GET method appends the data to the URL. And the length of a URL is limited. Maximum URL length is 2048 characters supported by latest browsers.

POST is used to pass sensitive data as it’s not appended and displayed within the URL. There is no limitation as to how much data can be passed using a POST method.

Move Forward with a Cisco Storage Networking Certification

Take your career to the next level with an expert exam in the Storage Networking field. Cisco provides a written and lab exam, both of which must be completed in order to obtain the CCIE certification. Because storage networking information is direct and to-the-point, the expert certification is the only one offered. Even so, it is held to the highest degree of respect just as other expert exams under the Cisco name. Career possibilities with this certification can greatly widen, and employers will take this certification as the greatest indication of skill and knowledge working with storage networking.

The overall exam is broken down into two sections (which can be taken at different times). The first section consists of a written, multiple-choice exam that tests basic and advanced storage networking concepts and features, such as design, technologies, applications, and management. The second section is a rather difficult eight-hour practical lab exam, which tests the ability to apply concepts and your knowledge learned to actual on-the-job scenarios. It is a fantastic way to prepare for the job field and understand exactly what such a job will entitle.

Both exams can be accompanied by ExamTrace, a training resource that works to teach and review specific exam details. It saves time that would otherwise be spent reading through information and learning knowledge that simply isn’t needed. The overall experience taking the storage networking expert exams can be wonderful. Cisco’s requirement of excellence is what makes their exams and certifications the bar by which companies operate. With Cisco exams, moving forward in your career could not be easier.
