Can someone give me a regular expression for a number to be between 1 and 5

Question

Can someone give me a regular expression for a number to be between 1 and 5, single digit

e.g. input has to be a number between 1 and 5 , 55 or 23 would not match

Answer 1

Try using anchors:

/^[1-5]$/

Explanation:

^     Start of line/string.
[1-5] A digit between 1 and 5.
$     End of line/string.

Answer 2

Would it not be simpler to check it as a number (ie if(x>=1 && x<=5) or something similar) rather than using a regex?
