Words to know
- JSON
- A common text format apps use to store and send data, made of names and values in { } brackets.
- Minify
- Removing spaces, line breaks and comments so code is smaller and loads faster. The computer reads it the same way.
- Beautify / format
- Adding line breaks and indentation so code is easy for humans to read. It does not change what the code does.
- cURL / API request
- cURL sends a request to a web address from the command line. APIs are web addresses that return data for programs.
