Code is as follows:
<body>
<a href="javascript:;" id="test">hello</a>
</body>
<script type="text/javascript">
document.getElementById("test").addEventListener("click", function () {
test()
}, false)
function test() {
var postTypes = new Array('hello', 'there')
(function() { alert('hello there') })()
}
</script>
This will throw an:
"Uncaught TypeError: object is not a function"
If I wrap the anonymous function call/invocation in another set of parentheses it will execute the alert, but still give me an error. If I put a semi-colon after the "var postTypes" definition then it will completely fine.
I was led to believe that javascript does not require semi-colons, so I'm making a guess that there is some weird associativity rules of function application that I am not fully understanding. Why am I getting this error?

I got a similar error and it took me a while to realize that in my case I named the array variable payInvoices and the function also payInvoices. It confused AngularJs. Once I changed the name to processPayments() it finally worked. Just wanted to share this error and solution as it took me long time to figure this out.
Try to have the function body before the function call in your JavaScript file.
I have this error when compiling and bundling TS with WebPack. It compiles export class AppRouterElement extends connect(store, LitElement){....} into let Sr = class extends (Object(wr.connect) (fn, vr)) {....} which seems wrong because of missing comma. When bundling with Rollup, no error.
I was getting this same error and spent a day and a half trying to find a solution. Naomi's answer lead me to the solution I needed.
My input (type=button) had an attribute name that was identical to a function name that was being called by the onClick event. Once I changed the attribute name everything worked.
<input type="button" name="clearEmployer" onClick="clearEmployer();">
changed to:
<input type="button" name="clearEmployerBtn" onClick="clearEmployer();">
Your code experiences a case where the Automatic Semicolon Insertion (ASI) process doesn't happen.
You should never rely on ASI. You should use semicolons to properly separate statements:
var postTypes = new Array('hello', 'there'); // <--- Place a semicolon here!!
(function() { alert('hello there') })();
Your code was actually trying to invoke the array object.
