TextPlugin

Tweens the text content of a DOM element, replacing it one character at a time (or one word at a time if you set the delimiter to " " (a space) or you can even use a custom delimiter). So when the tween is finished, the DOM element's text has been completely replaced. This also means that if you rewind/restart the tween, the text will be reverted. Here is a simple example of replacing the text in yourElement:

//replaces yourElement's text with "This is the new text" over the course of 2 seconds
gsap.to(yourElement, {duration: 2, text: "This is the new text", ease: "none"});

If you'd like to use a different delimiter so that instead of replacing character-by-character, it gets replaced word-by-word, just pass an object with configuration properties like this:

//replaces word-by-word because the delimiter is " " (a space)
gsap.to(yourElement, {duration: 2, text: {value: "This is the new text", delimiter: " "}, ease: "none"});

You can even add a new css class to the new text as it comes in. Learn more in the TextPlugin documentation.
