String

In JavaScript, the includes() method can be used to determine whether a string contains a specific value as a substring. The method returns a boolean value, true if the string includes the specified value, and false otherwise. Here are a few examples to illustrate its usage: 'JavaScript'.includes('Script') // true 'JavaScript'.includes('script') // false 'JavaScript'.includes('JavaScript') // true 'JavaScript'.includes('aSc') // true 'JavaScript'.includes('C++') // false In the first example, 'JavaScript' contains the substring 'Script', so the includes() method returns true....

In Python, there are a couple of approaches you can take to check whether a variable is a string. The two common methods involve using the type() function and the isinstance() function. Method 1: Using the type() Function To determine if a variable is a string using the type() function, follow these steps: name = "Roger" if type(name) == str: print("The variable is a string.") else: print("The variable is not a string....

Learn about the various properties and methods of the JavaScript String object. The String object has a static method called String.fromCharCode() that allows you to create a string representation from a sequence of Unicode characters. You can use this method to build a simple string using ASCII codes. Example: String.fromCodePoint(70, 108, 97, 118, 105, 111) //'Flavio' You can also use octal or hexadecimal numbers: Example: String.fromCodePoint(0x46, 0154, parseInt(141, 8), 118, 105, 111) //'Flavio' All the other methods described in this article are instance methods, meaning they are run on a string type....

Learn how to convert data types in JavaScript In JavaScript, although it is a loosely typed language, there may be instances where you need to convert values from one type to another. JavaScript has these primitive types: Number String Boolean Symbol and the object type: Object (plus null and undefined, but there’s no point in casting from/to them) Let’s explore different techniques for converting from one type to another. We’ll cover the most common scenarios....

Python, a versatile programming language, provides a range of built-in types to handle different kinds of data. In this blog, we will explore the basics of Python data types and how to work with them effectively. String Strings are sequences of characters enclosed in quotes (’’ or “”). To check if a variable is of the string data type, you can use the type() function or the isinstance() function: name = "Roger" type(name) == str # True isinstance(name, str) # True Numbers Python supports two types of numbers: integers (int) and floating-point numbers (float)....

The repeat() method in JavaScript, introduced in ES2015, allows you to repeat a specified string a certain number of times. It can be useful in situations where you need to generate repetitive patterns or output repeated text. Here’s an example of how to use the repeat() method: 'Ho'.repeat(3); // 'HoHoHo' In this example, the string “Ho” is repeated three times, resulting in the output “HoHoHo”. If you call the repeat() method without any parameters or with a parameter of 0, it will return an empty string:...
