What is Database?

 12 JavaScript Interview Questions   1)  What is the difference between the operators '= =' and '= = =' ?     = = compares two variables irrespective of data type while = = = compares two variables in a strict check. Example : document.write(9 = = "9") ;      //  true                                                                                     document.write(9 = = = "9") ;  // false     2) How to Empty an Array in JavaScript ? This code will clear the existing array by setting its length to 0. Example : arrayList.length = 0;   3) What is a higher-order function ?   Higher-order function is a function that accepts another function as an argument or return value. Example :  const firstOrderFunc = ( ) => console.log ( 'Hello I am a First order Function' );                      const higherOrder = ReturnFirstOrderFunc =>ReturnFirstOrderFunc ( );                                higherOrder (firstOrderFunc);    4) Difference between l

  The latest version the java Development Kit , Java 11 is out. 0 What are the key changes ? New Features First , What new features have been added in the 4 and a half years between the two versions ? 1) Var Keyword  :  The developer - friendly var keyword that came with Java 10 is another feature which helps to reduce the boilerplate coding . By only affecting local variables , the type Inference stope you repeating the same text over and over again. 2) Version String Schema :  Another between the two version is how the version strings are formatted. Versions will not be using a new schema of so   <major>.<minor>.<security>   that rather than something like 11u31 , where the security patch in unknown , you can find out simply by looking at the last value. 3) Modularity :  One of the biggest changes is the modularity introduced with Java 9. Modularity allows for you to split your application into different modules , but also changes how Java handles its API internally

Speed Limitations   Speed has always been the key focus of a programmer and will always be an essential criterion to work on. Python is an interpreted languages and therefore is slower in execution than other languages like C/C++ , java , or newer languages like Juila. For Python, the execution takes place with the help of an interpreter instead of a compiler , and that causes it to slow down. Memory Consumption App development and computing programs are memory-intensive tasks , and due to high memory consumption by Python , it isn't considered a right choice for memory-intensive jobs. Python's high memory consumption is also due to the flexibility of data types. Difficult To Blend In Python is a very addictive language , and Python lovers get so accustomed with its features and extensive libraries that become difficult for them to learn or work on  other programming language. According to Python experts, , declaring of cast "values" or variable "types" , a

  Python History Python laid it's foundation in the late 1980s The implementation of Python was started in December 1989 by Guido Van Rossum at CWI in Netherland. In February 1991, Guido Van Rossum published the code to alt.source. In 1994, Python 1.0 was released with new featured like lambda , map , filter and reduce. Python 2.0 added new feature such as list comprehensions , garbage collection system. On December 3 , 2008, Python 3.0 [also called "Py3K"] was released. It was designed to rectify fundamental flaw of the language. ABC programming languages is said to be the predecessor of Python language , which was capable.

  1.   Learning Web Developing is intimidating. There are so many resources and tutorials that it might seem overwhelming. So, let's example the common mistakes that we can make. 2.     Relying on JS framework and libraries While knowledge of, and ability to work with, popular JavaScript frameworks and libraries are marketable skills to have , you must also have a good knowledge of JavaScript.  If you fail to learn the foundations of JavaScript , you never truly learn what the features of these framework are doing under-the-hood 3.   Relying on Bootstrap Many developers starting out view Bootstrap as an easy way to style a web application , and while it can be useful in specific circumstances , it should not replace your knowledge of CSS and responsive web design. 4.  Not Modularizing your Code It's extremely important to ensure your code is modular, do not put it into one HTML file. Not only is it bad practice to have HTML, CSS and JavaScript into one file, it's messy and
