 ### Q: What is the importance of `config.js` file?
-A: `Config.js` files are text files that hold essential program information. They are structured for user configuration.

For instance, if an application only needs to store a user's preferred name, the config file might look like this:
+A: `Config.js` files are text files that hold essential program information.A config.js (short for configuration) file is like a settings file for an application. Instead of changing the code every time you want to adjust how the app works, you can simply update values in this file.

 However, most applications require multiple settings, so config files often contain key-value pairs for various options:
 ```
 NAME='Divya'
-SURNAME='Reddy'
+apikey='122hshjdhjd738emsi83wi8@@@###'
