How to Append a Character to end of a String in JavaScript ?

To append a character to the end of a string in JavaScript, you can use string concatenation with the + operator or the += operator.

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use string concatenation with the + operator to append the character '!' to str1.
Finally, we print the modified string to the console.

let str1 = "Hello World";
str1 += '!';
console.log(str1);

Hello World!

In this example,

let str2 = "How are you";
str2 += '?';
console.log(str2);
