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&…

CSS Text and Font

    In this post today, we will take a look at some of the most interesting CSS text and font properties listed below.
  • text-transform
  • white-space
  • word-break
  • word-spacing
  • word-wrap
  • font-variant


Text-transform property:

    Let's begin with the text-transform property. The filler text used in all the examples below has been taken from Andy Matthew's filler text generator which is a humorous replacement to the traditional boring lorem ipsum.

    The text-transform property will turn your text to uppercase, lowercase and also will capitalize the first character of every word. So now you don't need any javascript to do your bidding. This transformation will be done irrespective of the special characters preceding and following the text characters. The following example will make things much more clear and editable of course =)


White-space property:

    The next property to explore is the white-space property. The white-space CSS property is more of a replacement to the "pre" tag in HTML with some added advantages as well. The various values of the white-space property like the nowrap, pre, pre-line and pre-wrap will handle the white spaces and new lines differently. The following example will clearly define the value that this property gets to the table.


    As you can see in the example above, "nowrap" will not allow text or other inline elements to break naturally to the next line, but instead will push the boundaries of its parent until the line is completed, putting everything on a single line.

    The value pre works exactly as you would expect: The same as content wrapped inside the pre tags. All spaces and line breaks are honored, creating output in the browser that is virtually identical to what is in the markup. Also just like the pre tag, if everything in the markup is on a single line, the line will push the boundaries of its parent to keep everything in the output on a single line.

    The value pre-line will work exactly as normal with just one change. Line breaks in the HTML will be honored. So, if you have multiple spaces between elements, those will be ignored as usual, but if in your markup you drop to a new line, the new line will also occur in the output.

    The last value pre-wrap will work exactly as pre except that it will naturally wrap lines according to the boundaries of its parent. So it will not force everything on a single line to imitate what's in the markuo, but it will honor multiple spaces and explicit line breaks.

Word-break property:

    Let's explore the word-break property now. This property has 1 main value that we will discuss - the break-all value. Let us take a look at the example below.


    In the example above, I have put a border and width on the paragraph to demonstrate the usage of the word-break property. As you will notice in the first para, line breaks in text can only occur in certain spaces, like when there is literally a space or a hyphen. However, when you set the word-break property to break-all line breaks will occur between any character, as seen in the second para in the example above.

Word-spacing property:

    The word-spacing property helps to add space between words in a paragraph. The syntax is pretty simple and is as follows.

word-spacing: 10px;

Word-wrap property:

    The word-wrap property has a very useful value break-word. This value forces long words or sentences with no logical space or hyphen to wrap to the next line. The following example will make this much more clear.


    Note: If you have followed the post right upto this point, then you must be wondering that word-wrap: break-word and word-break: break-all are doing the exactly same thing. Aren't they? Well, these 2 things are slightly different and you can check the details on this post here.

Font-variant property:

    In font-variant there is one important value small-caps. In a small-caps font all the lowercase characters are converted to uppercase characters. However the uppercase characters are a font size smaller than the original uppercase character in the text. The following example will make things much more clear.


    This concludes our article today. Do let me know your thoughts on it. Do drop a line if this has helped you or even if you have found a mistake or would like to suggest something to better this post. Till the next post, happy coding!

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…
