How to create self string using special characters?

Creating self-string using special characters in JavaScript is a useful technique for adding unique and dynamic elements to your code. In this article, we will explore several methods for creating self-strings using special characters in JavaScript, including the use of escape characters, template literals, and the String.fromCharCode() method.

Escape Characters: One way to create self-string using special characters in JavaScript is by using escape characters. An escape character is a backslash () that is used to indicate that the character following it should be treated as a special character.

Example: To create a self-string that includes a newline, you would use the escape character followed by the letter “n”:

C++

#include <iostream>

int main() {
std::string selfString = "This is a self-string\nwith a newline.";
std::cout << selfString << std::endl;
return 0;
}

Javascript

var selfString = "This is a self-string\nwith a newline.";
console.log(selfString);

C#

using System;

public class GFG {

    static public void Main()
    {

        string selfString
            = "This is a self-string\nwith a newline.";
        Console.WriteLine(selfString);
    }
}
// code by ksam24000

Output

This is a self-string
with a newline.

Other common escape characters include “\r” for a carriage return, “\t” for a tab, and “”” for a double quote.

Template Literals: Another way to create self-string using special characters in JavaScript is by using template literals. Template literals are a new feature in JavaScript that allows you to create strings using template expressions. These expressions are enclosed in backticks ( ` `) rather than single or double quotes.

Example 1: To create a self-string that includes a variable, you would use template literals like this.

Javascript

var name = "John";
var selfString = `Hello, ${name}!`;
console.log(selfString);

Output

Hello, John!

Example 2: You can also use template literals to create self-string with special characters, like this:

Javascript

var selfString = `This is a self-string
with a newline.`;
console.log(selfString);

Output

This is a self-string
with a newline.

String.fromCharCode() Method: Another way to create self-string using special characters in JavaScript is by using the String.fromCharCode() method. This method is used to create a self-string from a series of Unicode character codes. For example, to create a self-string that includes a copyright symbol.

Example 1:

Javascript

var selfString = String.fromCharCode(169);
console.log(selfString);

Output

©

Example 2: You can also pass multiple character codes to create multiple special characters at once,

Javascript

var selfString = String.fromCharCode(169, 174, 8482);
console.log(selfString);

Output

©®™

Conclusion: In conclusion, creating self-string using special characters in JavaScript is a useful technique for adding unique and dynamic elements to your code. You can use escape characters, template literals, and the String.fromCharCode() method to create self-strings that include special characters like newlines, tabs, and special symbols. Practice with different combinations and possibilities to master this technique and enhance your coding skills.
