In this tutorial, we will learn how to print half diamond star pattern using Go programming language. Syntax for initialization; condition; update { statement(s) } To use a for loop in go lang we first need to initialize a variable then specify the condition of the loop i.e when should the loop end then we need to increment or decrement the variable followed by the lines of codes that should get executed. Example 1: Golang Program Code to print Half Diamond Star Pattern Using a Single Function Approach The goal is to divide the pattern into ... Read More
In this article we will discuss about how to get real part from a complex number in Go language. A complex number in mathematics is a number that can be expressed in the form of a + ib where i is called iota. The value of iota is $\mathrm{\sqrt{-1}}$ and a and b are real numbers. The first part i.e ‘a’ is called real part of complex number and the part after iota i.e ’b’ is called imaginary part of complex number. Syntax func real(number complex128) float64 The real() function is used to get the get the real part ... Read More
In this tutorial, let us discuss the basic rules for JavaScript parameters. A JavaScript function is a code that performs a particular task. The function parameters are the name list in the function definition. Parameters are also known as formal parameters or formal arguments. We can follow the syntax below to declare parameters. Syntax function functionName(param1, param2) { } When there is no value for a parameter, a default value comes in place. Rules Declare the default parameters as the final ones to avoid an error. The JavaScript function definition does not specify a parameter type. The JavaScript ... Read More
In this tutorial, we will learn what are the different types of DOM available to access and modify content in JavaScript. The Document Object Model (DOM) is a data representation of the objects that form the structure and content of a web document. It is an interface for scripting web pages. Programs can alter the document’s structure, style, and content by utilizing the DOM. The DOM represents each element as a node, and the programming languages like JavaScript can easily interact with the nodes to modify the page. There are different types of DOM available to access and modify content ... Read More
In this tutorial, we will learn the best practices to follow while using JavaScript. JavaScript is used in almost every website to make it more user interactive. Throughout the years, ECMAScript has released different versions of JavaScript. Each version has enhanced functionalities and new features, so it is important to know the best practices to follow while using JavaScript. The following are the best practices to be followed while using JavaScript − Meaningful Variable and Function Name The variables’ and functions’ names should be meaningful to their uses. In JavaScript, we use the variable to store some data, and the ... Read More
In this tutorial, we will learn complex data types in JavaScript. JavaScript has multiple built-in data types to store data in different formats. The data types of JavaScript can be divided into two groups, and those are primitive data types and non-primitive data types. Number, String, Boolean, Undefined and Null are part of the primitive data type, whereas the Array and Object are part of the non-primitive data type. The typeof operator is used to identify the data types. The primitive data types are simple and easy to use. In contrast, the non-primitive data types (Array and Object) are relatively ... Read More
In this tutorial, we will learn about native objects in JavaScript. Native JavaScript objects are regular JavaScript objects offered by JavaScript itself. Inbuilt objects, pre-defined objects, and global objects are other names. No matter the computer or environment, all users have access to these objects, and they function similarly. They may be used as both constructors (like String(), Array(), and Object()) and primitive values since their functions are unaffected by changes to the machine or environment. An object in an ECMAScript implementation whose semantics are entirely determined by this specification as opposed to the host environment. Native objects are additionally ... Read More
In this tutorial, let us discuss the function scope and context in JavaScript. Functions are the building blocks of Javascript. Therefore, JavaScript is a functional programming language. Scope The 'scope' is the code space where we can define and use a variable in a function. Scopes are of four types. Global scope Global 'scope' is the default scope. A variable with global 'scope' is accessible throughout the program. Browser closing removes a global variable. Window objects can access var variables wherein they can't access the let variables. Functional or local 'scope' A function variable is accessible only with the function. ... Read More
In this tutorial, let us discuss the smart, self-overwriting, or lazy-getters in JavaScript. A getter binds the property of an object to a function, but the getter will not calculate the property value until we access it. The getter helps when we need to get some dynamic value without an explicit call. Users can follow the syntax below to work with the getters. Syntax { get prop() {} } { get [exp]() {} } The prop and the exp are the object's properties that bind to a function. 'prop' is a simple object property, and 'exp' is an expression. ... Read More
In this tutorial, let us look at how to set whether the table border should collapse into a single table border or not with JavaScript. We can use the borderCollapse property in JavaScript to accomplish this. Let us look into this in brief. Using the Style borderCollapse Property The borderCollapse property defines whether the table border should collapse into a single table border or separate into a double table border. The value 'separate' is the default. The borderCollapse is a read-and-write property. Users can follow the syntax below to use the borderCollapse property. Syntax object.style.borderCollapse = "separate|collapse|initial|inherit|revert|unset" The syntax ... Read More
