If you have a number with a leading zero, like 010 or 02, how to remove that zero?
If you have a number with a leading zero, like 010
or 02
, how to remove that zero?
There are various ways.
The most explicit is to use parseInt()
:
parseInt(number, 10)
10 is the radix, and should be always specified to avoid inconsistencies across different browsers, although some engines work fine without it.
Another way is to use the +
unary operator:
+number
Those are the simplest solutions.
You can also go the regular expression route, like this:
number.replace(/^0+/, '')
