+Converts a string to camelcase.
+
+- Use `re.sub()` to replace any `-` or `_` with a space, using the regexp `r"(_|-)+"`.
+- Use `str.title()` to capitalize the first letter of each word and convert the rest to lowercase.
+- Finally, use `str.replace()` to remove spaces between words.
+
+```py
+from re import sub
+
+def camel(s):
+  s = sub(r"(_|-)+", " ", s).title().replace(" ", "")
+  return ''.join([s[0].lower(), s[1:]])
+```
+
+```py
+camel('some_database_field_name') # 'someDatabaseFieldName'
+camel('Some label that needs to be camelized')
+# 'someLabelThatNeedsToBeCamelized'
+camel('some-javascript-property') # 'someJavascriptProperty'
+camel('some-mixed_string with spaces_underscores-and-hyphens')
+# 'someMixedStringWithSpacesUnderscoresAndHyphens'
+```
