The challenge is the following:
Take a look at the app.js and preview. The aim of this application is to show what the user types in to the input field and preview it in the H1 tag. Almost all the code is there, there's just one thing missing. Retrieving the value from the input.
//Select the input for the title for blog post. var $titleInput = $("#title");
//Select the preview h1 tag var $previewTitle = $("#titlePreview");
// Every second update the preview var previewTimer = setInterval(updatePreview, 1000);
function updatePreview(){
//Get the user's input
var titleValue;
//Set the user input as the preview title.
$previewTitle.text(titleValue);
}
Could you help me please?

The jQuery .val() method is good for obtaining the contents of an input field.
And the variable $titleInput already exists to conveniently reference the input field.
