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&…

Better Late, Than Never

    A huge announcement from the members of the jQuery Mobile development team came in late last week! Amongst huge speculations that the extremely popular jQuery Mobile project was not being worked upon and that there would be no more versions or updates, the jQuery Mobile team lead has announced that the project is pretty much alive and being worked on!


    What a huge sigh of relief for jQuery Mobile lovers like myself! They are working on the next version of jQuery Mobile - 1.5 and though they have not committed on a final date of release, it is pretty certain that the newest version of the popular mobile web framework will soon see the light of day. There are some pretty huge things happening on the jQuery Mobile project and you can read the original blog post on the jQuery Mobile website. If you want the highlights, continue to read on!

  1. jQuery UI and jQuery Mobile will now share components. jQuery Mobile now shares the new and improved jQuery UI core. This clearly means that, all the developers out there who wanted to consume the jQuery UI components or widgets into jQuery Mobile web applications, will now have it ready out of the box.
  2. The upcoming version v1.5 will not have all the jQuery UI widgets, but will eventually have complete integration.
  3. jQuery Mobile will finally have in-built support for draggable, droppable and sortable from jQuery UI.
  4. The work on auto-enhancement that began in 1.4 continues in the new version too, with data-role becoming it's own stand alone module.
  5. The love story with jQuery UI continues - The 2 projects are merging their testing infrastructure too.
  6. In the future, not in v1.5, the 2 projects will also merge their efforts to build a common theme and theme roller.
  7. jQuery Mobile is taking a huge step towards improving their touch support. To this end, they will be teaming up with the very popular Hammer,js library and also joining efforts with Pointer Events Polyfill (PEP).
  8. A huge step in browser support. The framework will no longer support the older browsers and older OS versions. The framework will now be supporting the recent and the latest browsers and mobile OS versions.
  9. In the upcoming version, no workarounds or bug fixes for these older browsers and older OS versions, would be removed, but moving towards v1.6 these things would be removed. This clearly means that jQuery Mobile will be losing some weight and will be getting much lean and healthier :)

    This gives us a clear idea that jQuery Mobile is working towards making huge improvements to the framework and we can expect to see huge changes in the upcoming versions. Keep your excitement up and following the jQuery Mobile framework.

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…
