Regex for range from 1 to 10

A range of numbers is a set of numbers that falls within a certain range or span. It is defined by the minimum and maximum values of the set. For example, the range of the numbers 1, 2, 3, 4, ... 10 is 1 to 10. The minimum value in this range is 1, and the maximum value is 10. In this article let's understand how we can create a regex for month and how regex can be matched for a given month name.

Regex (short for regular expression) is a powerful tool used for searching and manipulating text. It is composed of a sequence of characters that define a search pattern. Regex can be used to find patterns in large amounts of text, validate user input, and manipulate strings. It is widely used in programming languages, text editors, and command line tools.

2nd Alternative 10
10 matches the characters 10 literally (case sensitive)
$ asserts position at the end of a line
Global pattern flags
g modifier: global. All matches (don't return after first match)
m modifier: multi line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)
