Why is my replace method not working?

JavaScript
1 
function convertHTML(str) {
const newStr = str;

for (let i = 0; i < newStr.length; i++) {
  switch(newStr[i]) {
    case "&":
      newStr.replace(newStr[i], "&amp;");
      break;
    case "<":
      newStr.replace(newStr[i], "&lt;");
      break;
    case ">":
      newStr.replace(newStr[i], "&gt;");
      break;
    case `"`:
      newStr.replace(newStr[i], "&quot;");
      break;
    case `'`:
      newStr.replace(newStr[i], "&apos;");
      break;
  }
}

return newStr;

The replace method returns a new string, it does not change the original string.

Oh damn, that’s true. It’s a bit tricky for me to keep up with which methods in JS return new ones versus those that modify the original. Thanks.
