# [TrimKit](https://gitlab.com/explorigin/trimkit)
|
|
|
|
TrimKit is a set of DOM and API abstactions for the purpose of better Javascript minification. For
|
|
example:
|
|
|
|
if (a === undefined) { alert('Oops'); }
|
|
|
|
minifies down to:
|
|
|
|
if(a===void 0){alert('Oops')}
|
|
|
|
If we compare against undefined more than 3 times, we can save bytes by doing this:
|
|
|
|
function isUndefined(a) { return a === void 0; }
|
|
|
|
if (isUndefined(a)) { alert('Oops'); }
|
|
|
|
which minifies down to:
|
|
|
|
function b(a) { return a === void 0; }
|
|
|
|
if (b(a)){alert('Oops');}
|
|
|
|
With enough uses of common APIs, you can win back some bytes.
|
|
|
|
NOTE: TrimKit will help you obsess about Javascript file sizes but that does not always translate to
|
|
smaller files after you apply compression. Because files using have more entropy, small,
|
|
pre-compression gains can result in after compression losses. YMMV.
