How To Create A JavaScript Typewriter Using Pure Vanilla JavaScript?


You must have seen the Text Typewriter Effect on many website sliders or in a heading that looks like a full effect of typing animation character by character in typewriter effect. So we decided to make it a little snippet to let you use it on your web pages also to give your web page an awesome effect.

For programmer if we discuss this code in detail then We do not recommend it as it uses setTimeout(). Anything using setTimeout() or setInterval() slows down the page. Still, as it was a temporary landing page, this is how I approached it. The HTML structure is pretty simple and all details are contained into data parameters. I’d say it’s relatively safe for SEO.

There are many code snippets available online or on many other blogs and websites but everyone is not able to optimize your blog or website so you need some optimized code snippet. So now checkout out the code snippet for your blog and website that will give you all features for your desired code. Now grab the ready to use code and paste it where you want.
