Question 280826 in Javascript Question posted in
A very good W3school tutorial can be found here.

how to check the whitespace in string and convert it into array – Javascript

var convertToArray = (txt) => {
  let arr = txt.split(" ");
  console.log(arr);
};

convertToArray("Hello World   ");

At the end of Hello World I have 4 spaces and now I need to take that whitespace as element of an array.

E.g.: ["Hello", "World", " "]

    You should use this code:

    var convertToArray = (txt) => {
  let arr = txt.split(/s+/); // Use regular expression to split by one or more spaces
  console.log(arr);
};

    Use match instead of split and filter out the single spaces. Something like:

    var convertToArray = (txt) => {
  let arr = txt.match(/b(.+?)b|s{2,}/g)?.filter(v => v !== ` `);
  console.log(JSON.stringify(arr));
};

convertToArray("Hello World   ");
convertToArray("   Hello World   And Bye again   ")
