Log Levels
10 Points
strings
Instructions
In this exercise you'll be processing log-lines.
Each log line is a string formatted as follows: "[<LEVEL>]: <MESSAGE>".
There are three different log levels:
INFOWARNINGERROR
You have three tasks, each of which will take a log line and ask you to do something with it.
1. Get message from a log line
Implement the message function to return a log line's message:
message "[ERROR]: Invalid operation"
// => "Invalid operation"Any leading or trailing white space should be removed:
message "[WARNING]: Disk almost full\r\n"
// => "Disk almost full"2. Get log level from a log line
Implement the logLevel function to return a log line's log level, which should be returned in lowercase:
logLevel "[ERROR]: Invalid operation"
// => "error"3. Reformat a log line
Implement the reformat function that reformats the log line, putting the message first and the log level after it in parentheses:
reformat "[INFO]: Operation completed"
// => "Operation completed (info)"Log Levels
