remove all text in brackets javascript

Any suggestion on how to remove text content in brackets?

Example:

<span id="new">Welcome [something.....] home</span>
<span id="new">The Jeep is (asdjfl... ect) nice</span>

var myString = document.getElementsByClassName('new')[0];
myString.replace(/ *\[[^\]]*]/, '');

Goal:

• Welcome home
• The Jeep is nice
