I tried to use the parse() function of JSLint to parse three pieces of JavaScript code:

1. function(b, c){var a = b + c; return a; }
2. window.addEventListener('click', click_hanlder, true);
3. document.documentElement.innerHTML;

Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse();

var source = "something to parse";//replaced by the code above

tree = parse(source);

if (tree) {

    document.write(JSON.stringify(tree, ['key', 'name', 'message',
        'value', 'arity', 'first', 'second', 'third', 'fourth'], 4));
}

} catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } `

The output:

1. returns a correct tree.
2. returns a tree with only one node of "window".
3. crashes the browser.

I'm wondering whether JSLint doesn't support DOM function.
