I'm trying to make a string that will write itself letter by letter until completing the sentence, and the speed of appearing each letter is based on an input that varies from 1 to 10. At the end of the string, it will blink for 5 seconds until that an alien will appear. My idea was to create a setInterval to add the letters and when the counter added the array size it would return the final animation of the loop with the new setInterval call, and before it was called again it had already been cleared, and called again in a recursion by setTimout callback to maintain the infinite loop. But it's not reaching setTimout, why?

In this app, When i submit a word (for eg help) for the first time then it will return the search results and renders it on the page, but if i searched for another word then the results wont be displayed until and unless i refresh the page.

I'm trying to make a landing page comparison slider that reacts on the mouseX position, but I want the slider to move the opposite direction of the mouse position. Any suggestions on how I can make that happen?

Demo: https://jsfiddle.net/uw5v94qf/

So basically, like the demo shows, in my case the slider follows the mouse position. But I want it to kind of do the opposite(?), that is revealing the current slide that the mouse is hovering. The more the mouse moves towards the edge, the more it shows that particular slide.

With the help of the comunity (Thanks all of you !) I manage to create 3 fields at a time in a single row, anytime the user needs it. The thing is that everytime it create the fields, the placeholder is always "Another field". I would like that instead of that says Infrastracture, Time, Monthly Cost", but I have no clue how to do that.

Thank you Kindly !
