Shedding a string off whitespaces in JavaScript

We are required to write a JavaScript function that takes in a string and returns a new string with all the character of the original string just the whitespaces removed.

Example

The code for this will be −

const str = "This is an example string from which all whitespaces will be
removed";
const removeWhitespaces = str => {
   let newStr = '';
   for(let i = 0; i < str.length; i++){
      if(str[i] !== " "){
         newStr += str[i];
      }else{
         newStr += '';
      };
   };
   return newStr;
};
console.log(removeWhitespaces(str));

Output
