The first thing that comes to our mind is dealing with data types. To talk about data types one developer should have knowledge upon- Number, String, Boolean, Function, Object, Null and undefined. There is also sub-section in Object data type which are Function, Array, Date and RegExp are worth mentionable.
parseFloat('123', 10); //123
parseInt('0`0', 10); //10
Number.isNaN(); //Determined whether the number is NaN
'hello'.charAt(0); // "h"
'hello'.concat(' world'); // "hello world"
'Hello'.toLowercase; // 'hello'
'hello'.toUppercase; // 'HELLO'
Math.ceil(7.004); // returns 8
Math.floor(6.95); // returns 6
Math.round(); // range 0 to 1
['apple', 'banana'].push('mango'); // ['apple', 'banana', 'mango']
['apple', 'banana', 'mango'].pop('mango'); // ['apple', 'banana']
['apple', 'banana'].length; // 2
['apple', 'banana', 'mango'].shift(); // ['banana', 'mango']
['a', 'b', 'c'].reverse(); // ['c', 'b', 'a']
5. It’s haloween day. You are knocking on someones door. Trick or treat!? As a treat you got a packet of chocolates. You are excited to open the packet. You are shocked by seing whats inside! Its empty ‘null’. You got tricked. By now you got idea what’s null is in a programming language. It means empty value in a variable. Let’s see some examples-
const str = null;
// output: null
6. Besides null there is also a similar type of data type called Undefined. When a variable is declared but not initialized at that time the value is set undefined.
// output: undefined
A beginners guide to SSL: When you navigate to websites have you ever seen something like http & https? Have you noticed the difference between http & https? Yes your are right the char S. It may seem only a single character or some minor things. But its not. This ‘s’ makes a huge diffence in modern Web applications. To figure this out we have to know what is SSL. SSL stands for ‘Secure Socket Layer’. Websites with hypertext containing https is more secure and encrypted. Next time you visit a site be sure about its security.
That’s enough enough for today folks. See you on some other stories. Good day paul. Happy coding.
