I ran into an issue while working on my TSX markup. The TS typechecker in Vim is giving me the error message

Any suggestions on how to resolve this error message? Would casting the input variable to a different type help?
My solution involved the following steps:
input.setAttribute('style', 'white-space: pre; position: absolute; left: -9999px;');
It was pointed out in a similar response on Stackoverflow that "TypeScript does not have a style property on Element."
Another option is to utilize input.style.cssText
input.style.cssText = "white-space:pre; position:absolute; left:-9999px;";It turns out, I already had the solution ...
Specifying the input variable as a specific type resolved the issue.
const input: HTMLTextAreaElement = document.createElement('textarea')
const currentTarget = e.currentTarget as HTMLDivElement
This could be because createElement has the ability to create various elements and Typescript lacks the knowledge of which one specifically, given that it is determined by the input parameter. Therefore, it needs an explicit declaration of what it is returning.
What is the difference in appearance?
input.style.whiteSpace = 'pre';
input.style.position = 'absolute';
input.style.left = '-9999px';
One cannot change the <code style="color: blue;">stylesetProperty method.
To set a specific property and value for an element:
element.style.setProperty(propName, propValue)For instance, in your scenario:
input.style.setProperty("height", "10px")Check out more information here: https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleDeclaration/setProperty
