What is the result of adding a string and a number in JavaScript?

31-Oct-2023In JavaScript, when you add a string and a number using the + operator, JavaScript performs a type conversion, and the result is a string. The number is converted to a string, and then the two strings are concatenated.
Here's an example:
In this example, the number 5 is implicitly converted to a string, and then it's concatenated with the string "Hello," resulting in the string "Hello5."
It's important to note that JavaScript's dynamic typing allows you to perform operations like this, but you should be cautious about type conversions, especially when dealing with user input or data from external sources, to ensure that your code behaves as expected.
