Difference between == and === operator in JavaScript
JavaScript is widely used to create interactive web pages. It has many frameworks such as React JS, Angular JS, Node JS, etc. Like any other programming language, JavaScript also provides operators like arithmetic, relational, comparison operators, etc. The equality operator, i.e., "==" is one such comparison operator that checks whether the LHS is equal to RHS or not. This operator is present in all other programming languages but it is somewhat different in JavaScript. This is due to the fact that JavaScript is a loosely typed language, whereas all other languages are strictly typed. As JS is loosely typed, it ...
Read MoreWhat is the difference between jQuery and JavaScript?
Both JavaScript and jQuery serve the same overarching objective of making webpages more interactive and dynamic. They give websites a sense of vibrancy. People may ask why there is a need for two distinct concepts if they serve the same function. Read through this article to find out how jQuery differs from JavaScript. What is JavaScript? JavaScript is a lightweight programming language that is used most often as a component of webpages. Its webpage implementations enable client-side script to interact with the user and create dynamic sites. It is a programming language that is interpreted and can handle ...
Read MoreDifference Between PHP and JavaScript
JavaScript and PHP are two of the most widely used programming languages for web development. PHP is primarily a server-side scripting language that handles backend operations, while JavaScript is a client-side scripting language that manages frontend interactions and user experiences. Since PHP is derived from the C programming language, it is relatively easy to learn for developers with a solid foundation in C. Both languages serve different purposes in web development, each with unique advantages and specific use cases. What is PHP? PHP is a general-purpose scripting language primarily designed for web development. Created in 1994 by ...
Read MoreDifference between DBMS and RDBMS
A DBMS (Database Management System) is software used to create, update, delete, and maintain a database with controlled access to data. An RDBMS (Relational Database Management System) is an enhanced type of DBMS based on the relational model, storing data in tables with defined relationships. What is a DBMS? DBMS stores data in the form of files using navigational or hierarchical structures. There is no relationship between data elements, so it does not support distributed databases. DBMS is often used in small organizations to deal with small amounts of data handled by a single user. Examples include file ...
Read MoreDifference between Primary key and Foreign key in Database
In a relational database, keys are the most important elements to maintain the relationship between two tables or to uniquely identify the data from a table. Primary key is used to identify data uniquely therefore two rows can't have the same primary key. It can't be null. On the other hand, foreign key is used to maintain relationship between two tables. The primary key of a table acts as the foreign key in another table. The Foreign key in a table helps enforce Referential Integrity constraint. Read this tutorial to find out more about Primary and Foreign keys and ...
Read MoreDifference between Function and Procedure
SQL (Structured Query Language) is a computer language which is used to interact with an RDBMS (Relational Database Management System). It is basically a method of managing, organizing, and retrieving data from a relational database. In SQL, two important concepts are used namely, function and procedure. A function calculates the results of a program based on the inputs provided, whereas a procedure is used to perform some tasks in a specific order. There are many other differences between functions and procedures, which we will discuss in this article. What is Function? A function, in the context of ...
Read MoreHow to Create a File in Linux from the Command Line?
Before getting into the ways of creating a file using Bash, let's first understand how Linux treats its files. Linux organizes all its data into files and files are organized into directories. Further, the directories are organized into tree-like structures called the file system. When you have to work in a Linux environment, you would definitely have to spend a lot of your time working on different types of files. There are several different ways in which one can create a file in Linux. You can create a file from the Bash Shell or you can use the Desktop File ...
Read MoreDifference between Compiler and Assembler
Both compilers and assemblers are the language processors used to convert software codes written in high-level language and assembly language into machine language codes. Compiler and assemblers are the types of system software. These are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. and assembly language. Therefore, it is necessary to convert an HLL or assembly code into machine code for execution. In this article, we will highlight all the key differences between compilers and assemblers. Let's start with some basics of compiler and assembler so that it will ...
Read MoreDifference between Synchronous Motor and Induction Motor
A motor in general is an electrical machine that converts electrical energy into mechanical energy. Electric motors can either be DC Motors or AC Motors, depending on the type of power supply that is supplied as its input.AC motors are further classified into two types−Asynchronous or Induction MotorSynchronous MotorA synchronous motor always runs at synchronous speed, while an induction motor runs at a speed less than the synchronous speed.Read through this article to find out more about synchronous motors and induction motors and how they are different from each other.What is a Synchronous Motor?A synchronous motor is a type of ...
Read MoreDifference between Synchronous and Asynchronous Sequential Circuits
Both Synchronous and Asynchronous Sequential Circuits are types of sequential circuits that use feedback for the next output generation. On the basis of the type of this feedback, both circuits can be differentiated. A sequential circuit is one whose output depends upon both present and past inputs. The classification of sequential circuits into synchronous and asynchronous sequential circuits is done on the basis of their triggering. In a synchronous sequential circuit, the changes in all the state variables are synchronized with the universal clock signal. In contrast, in an asynchronous sequential circuit, the changes in all the state variables are ...
