const container = document.getElementById("someElementId");
And then later in that same article the author uses:
let container = document.getElementById("someElementId");
It can elicit the pernicious WTF response followed by an emoji :-)
Like the article says the let syntax indicates that the value is to be changed which happens in the code snippet.
