) to match a range of characters is not limited to letters. It also works to match a range of numbers.
For example, /[0-5]/
matches any number between 0
and 5
, including the 0
and 5
.
Also, it is possible to combine a range of letters and numbers in a single character set.
let jennyStr = "Jenny8675309";
let myRegex = /[a-z0-9]/ig;
// matches all letters and numbers in jennyStr
jennyStr.match(myRegex);
h
and s
, and a range of numbers between 2
and 6
. Remember to include the appropriate flags in the regex.
myRegex
should match 17 items.
testString: 'assert(result.length == 17, "Your regex myRegex
should match 17 items.");'
- text: Your regex myRegex
should use the global flag.
testString: 'assert(myRegex.flags.match(/g/).length == 1, "Your regex myRegex
should use the global flag.");'
- text: Your regex myRegex
should use the case insensitive flag.
testString: 'assert(myRegex.flags.match(/i/).length == 1, "Your regex myRegex
should use the case insensitive flag.");'
