Regex is not validating

Question

My requirement is of "Minimum eight characters, at least one uppercase letter, one lowercase letter, one number and one special character" and the below code is giving me false.

 var pattern = new RegExp('/^(?=\S*[a-z])(?=\S*[A-Z])(?=\S*\d)(?=\S*[^\w\s])\S{8,}$/');
    var value = 'Abcde@12345';
    var message = '';
    
    if(value !==undefined ){
        
        
        if(!pattern.test(value)){
          
           console.log(false);
        }
        else{
           console.log(true);
        }
    }

Please suggest me any better solution for my requirment

You are mixing regey literals and strings. Try removing the / at start and end — DownloadPizza, May 20 '21 at 07:31
Similar to above, but remove the `'` and leave the `/` to get it to work https://jsfiddle.net/016d8th7/ — freedomn-m, May 20 '21 at 07:32
`var pattern = /^(?=[^a-z]*[a-z])(?=[^A-Z]*[A-Z])(?=\D*\d)(?=[\w\s]*[^\w\s])\S{8,}$/;` — Wiktor Stribiżew, May 20 '21 at 07:32

You are mixing strings with regex with new RegExp, Simply use this:

var pattern = /^(?=[^a-z]*[a-z])(?=[^A-Z]*[A-Z])(?=\D*\d)(?=[\w\s]*[^\w\s])\S{8,}$/;
