Regex not working in Vue2?

Question

Vue.js

I needed to do email validation and vscode highlights the regex as an error.
regex
in computed is regex:

computed:{
  regex(){
    return  new RegExp(/^(([^<>()\[\]\\.,;:\[email protected]"]+(\.[^<>()\[\]\\.,;:\[email protected]"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,24}))$/)

  }
},

validation:

if (!this.regex.test(this.email)) {
        this.emailErr = true;
        let vm = this;
        setTimeout(() => {
          vm.emailErr = false;
        }, 1000);

Yes, the creators of Vue cut regular expressions out of JS.
Try it:

computed:{
  regex(){
    return /^(([^<>()\[\]\\.,;:\[email protected]"]+(\.[^<>()\[\]\\.,;:\[email protected]"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,24}))$/;
  }
},

RegExp accepts a string, and you pass a regular expression
UPD : RegExp accepts regular expressions as well. Check the correctness of the expression
