  var str = "how;are;you;;doing;";
  var res = str.split(";");

  console.log(res[3]);
  console.log(res);

Try this:-

var str = "how;are;you;;doing;";

var filtered = str.split(";").filter(function(el) {
  return el != "";
});

console.log(filtered);

Output:

[ "how", "are", "you", "doing" ]

You can filter empty strings after splitting:

var str = "how;are;you;;doing;";

console.log(str.split(';').filter(Boolean));

You could do this

var a = "how;are;you;;doing;";
a = a.split(';').filter(element => element.length);

console.log(a);

The below function definition is in ES6:

let myFunction = () => {
  let str = "how;are;you;;doing;";
  return str.split(';').filter((el) => {
    return el != "";
  });
}

Now you can simply log the output of the function call.

console.log(myFunction());

Use split for converting in an array, remove blank space and then join an array using sep",".

function myFunction(str) {
  var res = str.split(";");
  res = res.filter((i) => i !== "");
  console.log(res.join(","));
}

var str = "how;are;you;;doing;";
myFunction(str);
