How do I capitalize all text in a document using the DOM and the toUpperCase function?

I want to capitalize every single paragraph in a website using the document.querySelectorAll() function.

I don't know what parameter to choose so I can get an array of all the texts.

Here is my Code:

var txtArr = document.querySelectorAll("p");

function capitalize(txtArr){

    for (var i = 0; i < txtArr.length; i++){
    
        txtArr[i].textContent.toUpperCase();
    
    }

}

capitalize(txtArr);

Maybe try

var txtArr = Array.from(document.querySelectorAll("p"));

function capitalize(txtArr) {
    for (var i = 0; i < txtArr.length; i++){
    
        txtArr[i].textContent = txtArr[i].textContent.toUpperCase();
    
    }

}

capitalize(txtArr);
