JavaScript - Add a Character to the Beginning of a String

These are the following ways to insert a character at the beginning of the given string:

1. Using String Concatenation

Directly prepend the character using the + operator or template literals.

*Hello, World!

2. Using Template Literals

String concatenation using + or template literals is an effective way to insert a character at the beginning of a string. This method creates a new string with the desired modification without altering the original string (since strings are immutable in JavaScript).

*Hello, World!

3. Using slice() Method

Extract the original string and append the new character to it by the use of slice() method.

*Hello, World!

4. Using Using splice() Method (Array-Based)

Convert the string to an array (as strings are immutable in JavaScript), use splice to insert the character at the beginning, and join it back into a string.
