Hi All,

Greetings!

Why we add empty string, I have come across multiple times but never understood the meaning. Please help me to understand below highlighted part. Why we used +'' here.

Hello Tejas,

I have seen people most of the time using this syntax to convert the type to string.

It works similar to "variable.toString()."

I hope this information helps you. Thank you.
