ES6 101 - Map

ES6 101 - Map
ES6 Map is the topic of today’s post which also is the 11th in the ES6 101 Series. Map is going to be fairly easy, so before jumping into it, if you want to look at other features we have covered so far, here is a quick list for your reference.Fat Arrow FunctionsLexical Declarations - LetLexical Declarations - ConstSpread OPeratorTemplate LiteralRest OperatorDefault parametersDestructuringFor…ofSetNow let’s see what Map has to offer. As opposed to Set (which by the way, I highly recommend reading), Map saves values as key-value pair. Let’s see for ourselves how this works!Example of ES6 Mapvar dummyMap = newMap(); dummyMap.set("1"); // Method is set as against add in ES6 Setconsole.log(dummyMap); // [["1",null]] dummyMap.set("1", "one"); console.log(dummyMap); // [["1","one"]] dummyMap.set("2", "two").set("3","three"); console.log(dummyMap); // [["1","one&…

Jquery Mobile - Touch Optimized, Jquery and HTML5 based web framework

    Jquery Mobile - The next level of "Write Less, Do More" mantra of Jquery. Just recently, I started working on a project using the Jquery Mobile framework and just instantly fell in love with it! Jquery Mobile gives immense power and flexibility to developers and enables truly cross-platform and cross-browser and multi-device development. I have just loved it and have decided to share my knowledge with the readers of Spatial Unlimited.



    Jquery Mobile is a touch optimized web framework for smartphones and tablets. It's a unified, HTML5-based user interface system for all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation. Its lightweight code is built with progressive enhancement, and has a flexible, easily themeable design. This is one reason why I love Jquery Mobile. It is easily customizable - no head-ace of themeing; Jquery Mobile does it for you.

    Instead of writing unique apps for each mobile device or OS, the jQuery mobile framework allows you to design a single highly-branded web site or application that will work on all popular smartphone, tablet, and desktop platforms. This is another reason for the growing popularity of this web framework. Jquery Mobile takes care of all the cross-platform, OS specific issues and is continuously improving the support. Jquery Mobile has a very good developer community adding to the fast progress and device support for the same.

    Jquery Mobile has a wide range of UI widgets and elements, all following a fluid design, that we will be taking a look at in the following posts. I am on my learning curve and hope to take several along with me and on the way learn a lot from the many web-gurus here. Hope you like this new initiative from Spatial Unlimited and continue to show your support by sharing the knowledge, suggesting things and correcting me if I go wrong anywhere.

ES6 101 - Spread operator

ES6 101 - Spread Operator
Welcome to the fourth post in the ES6 101 series and the topic of discussion today is the Spread operator or the dot dot dot operator.... It is not very common to call it the “dot dot dot” operator, but I just kind of like the ring to it! Also when you say “dot dot dot” it actually helps me visualize unpacking multiple gifts from a gift box. Wondering why I am taking about gifts and gift boxes and “dot dot dot”. Well, the spread operator... is actually more like unwrapping gifts from a gift box. The spread syntax allows an iterable such as an array expression to be expanded in-place. Let’s actually dive into some examples straight away. It is much more simpler that way!Examples of the ES6 Spread Operator ...Example #1Problem statement: Let’s write a function to display the sum of 3 numbers passed to it in an array.

We would have done this as follows in the old ES5 way. 😏var arr = [1,2,3]; functionsum(a,b,c) { var output = a + b + c; consol…

ES6 101 - Destructuring

ES6 101 - Destructuring ES6 Destructuring assignments is the topic of this post and we will take a look at what destructuring means and we will look at multiole examples to understand the concept. As the name suggests, using the destructuring syntax, we would be breaking down values in an array or properties in an object into seperate variables.Arrays and objects allow you create, on-the-fly various packages of data.let a = [1,2,3]; ES6 destructuring uses similar syntax, however the LHS will now be a variable that would hold the package that you need to create. Sounds complex? πŸ˜“ Not really, just move ahead to the example that follows and you should get the hang of it.let a = [1,2,3]; let [x,y] = a; // We are now assigning array 'a' to a new arrayconsole.log(x); // 1console.log(y); // 2let [m,n,o] = a; console.log(m); // 1console.log(n); // 2console.log(o); // 3This helps us clearly see what destructuring does for an array! It basically unpacks the values in the array a…

ES6 101 - For..of

ES6 101 - For..of This is the 9th post in the ES6 series and we have looked at a whole bunch of some amazing and highly productive ES6 features that you can start using right away! Here is a comprehensive list of all the features that we have covered so far. 😍Fat Arrow FunctionsLexical Declarations - LetLexical Declarations - ConstSpread OPeratorTemplate LiteralRest OperatorDefault parametersDestructuringNow let’s look at what for..if has to offer us. Essentially, for..of does exactly the opposite of what for..in does. Let’s see what the difference is.// Using for..inlet someVar = [1,2,3,4,5] for(let item in someVar) { console.log(item); // The index values would be consoled. } When you execute the above code snippet, you will observe that, you get all the index values 0 1 2 3 4 of the array in the console. If you had to get access to the values at these indexes in the array, you would have to add the following to the above snippet in the for..in loop.console.log(`${it…

ES6 101 - Set

ES6 101 - Set
This is going to be the 10th post in the ES6 101 series and the topic for today is Set. Set object is a collection of values and is iterable. One cool thing about the values in set is that these are unique. This means that a set can have a value only once. Moreover you can think of a set as an actualy set in Mathematics. We will see a few samples to understand this concept of set.Examples of ES6 SetCreating a new set and adding values to it.Let’s create a new set and add some values to it and then discuss it further.let dummySet = newSet(); // That's it! A new set object is created dummySet.add(1); console.log(dummySet); // [1] dummySet.add(1); console.log(dummySet); // [1] and not [1,1]. This is because, values in a set are unique. dummySet.add(2).add(3).add(4); console.log(dummySet); // [1,2,3,4] dummySet.add('The UnderTaker').add('John Cena'); console.log(dummySet); // [1,2,3,4,'The UnderTaker…
