I should get into the habit of listing the assumptions my code makes.
In the above example, the following assumptions are present:
- The target substring (in this example, "<^JIM_JONES>") must *always*
appear at the beginning of the string for the function to perform its task
- The target substring will *always* begin with "<^", will feature a "_"
between the two name elements, and will conclude with ">"
- There will only be two name elements within the target substring (ie will
match "<^JIM_JONES>" and "<^MARY_BETH>" but will not match "<^JIM>" or
"<^MARY_BETH_JONES>")
- The function will only replace the first incidence of the target
substring. In the eventuality that the target substring value appears
multiple times in the string being processed, all other instances will be
left unchanged.
- All other contents of the string being processed can vary without impact
on the function.
