Vanilla JavaScript version of jQuery .click

Question

So maybe I'm just not looking in the right places but I can't find a good explanation of how to do the equivalent of jQuery's

$('a').click(function(){
    // code here
});

in plain old JavaScript?

Basically I want to run a function every time an a tag is clicked but I don't have the ability to load jQuery into the page to do it in the way above so I need to know how to do it using plain JavaScript.

Html

<a href="something">CLick Here</a>
<a href="something">CLick Here</a>
<a href="something">CLick Here</a>

Javascript:

var anchors = document.getElementsByTagName('a');
for(var z = 0; z < anchors.length; z++) {
    var elem = anchors[z];   
    elem.onclick = function() {
        alert("hello");
        return false;
    };
}
