I've been attempting to create a regex pattern for a 16-bit signed integer (from -32768 to 32767) based on the information from this 32-bit integer reference.
So far, my attempt looks like this:
^-?([0-9]{1,5}|32[0-6]{3}|32[0-6]{2}|327[0-5][0-8])$|^(-32768)$
Unfortunately, it's not working properly.
Any suggestions or guidance would be greatly appreciated.
It is recommended to try using an `if` statement instead of regular expressions for better performance.
let numberPattern = /^(-?(\d{1,4}|[012]\d{4}|3[01]\d{3}|32[0123456]\d{2}|327[012345]\d{1}|3276[01234567])|-32768)$/;
// test
console.log("-32768", numberPattern.test("-32768")) ;
console.log(" -9876", numberPattern.test("-9876")) ;
console.log(" 9876", numberPattern.test("9876")) ;
console.log(" 32767", numberPattern.test("32767")) ;
console.log("-32769", numberPattern.test("-32769")) ;
console.log(" 32768", numberPattern.test("32768")) ;I have a list obtained from an external API through the use of axios.
