example of HTMLElement.addEventListener in typescript?

Question

can I get one? this is what I have, but I'm getting a red squiggly line:

let button = <HTMLElement>document.body.querySelector(".btn");
button.addEventListener("click", () =>{});//not sure what to do here.  I know its wrong though.

below is my tsonconfig

{
    "compileOnSave": true,
    "compilerOptions": {
        "noImplicitAny": true,
        "removeComments": true,
        "sourceMap": false,
        "target": "es5",
        "lib": [
            "es6",
            "dom"
        ]
    },
    "include": [ "**/*" ]
}

Answer 1

With your given tsconfig.json it compiles fine:

let button = <HTMLElement>document.body.querySelector(".btn");
button.addEventListener("click", () => { });

Your IDE is lying. Works fine in VSCode / alm 🌹

Answer 2

The issue was ReSharper. I disabled the plugin and it worked fine. For reference I have attached two picutres, the first with ReSharper enabled, and the second with it disabled.
