/^[134567890][124567890]{0,4}$/this first bit is 2 or the other bit is 3 does not match, is there any good way
bilibili"s on-screen rules written by himself, so he can only use one sentence as a rule.
match 0 to 5 digits
let reg = /^((?!23{2,})\d){0,5}$/
it should be like this / ^ (?! 23 {2pr 4}\ b)\ d {1jue 5} $/ , please try to verify the highly liked answer with 23334 or 2334.

0this kind of requirement is also rare, and it is difficult to match in the forward direction, so reverse matching is recommended.
var str = '2333';
var res = /(233+)/.test(str);
if(!res){
console.log('')
}else{
console.log('')
}think carefully about your requirements and add a sentence to judge the length
var str = '1233322';
var res = /(233+)/.test(str);
if(res && str.length <= 5){
console.log('')
}else{
console.log('')
}var arr=['1','12345','12334','12333','23333'];
var reg=/^(?!\d*23{2,})\d{5}$/;
console.log(arr.filter(item=>reg.test(item)))try this
