Given a string str, create a string consisting of all the non-alphabets and non-digits.

JavaScript code

let str='q#w2@B**g';
let len=str.length;
let alpha='';
let alpha1='';
let rest='';

let digits='';
for(let i=0;i<len;i++)
{
 if(str[i]>='a'&&str[i]<='z')
 {
  alpha=alpha+str[i];

 }
    else if(str[i]>='A'&&str[i]<='Z')
 {
  alpha1=alpha1+str[i];
 }
 else if(str[i]>='0'&&str[i]<='9')
 {
  digits=digits+str[i];
 }
 else
 {
  rest=rest + str[i];
 }
}
console.log(rest);
