||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object form, that is based on (or
|
||||
derived from) the Work and for which the editorial revisions, annotations, elaborations, or other
|
||||
modifications represent, as a whole, an original work of authorship. For the purposes of this
|
||||
License, Derivative Works shall not include works that remain separable from, or merely link (or

||||
bind by name) to the interfaces of, the Work and Derivative Works thereof.
|
||||
|

|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity on behalf of whom a

|
||||
hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform,

sublicense, and distribute the Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor
|

by combination of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a cross-claim or
|
||||
counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work
|
||||
constitutes direct or contributory patent infringement, then any patent licenses granted to You
|
||||
under this License for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or Derivative Works a copy of this License;
|
||||
and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices stating that You changed the
|
||||
files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works that You distribute, all
|
||||
copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding
|
||||
those notices that do not pertain to any part of the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative
|
||||
Works that You distribute must include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works, in at least one of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or documentation, if provided along with
|
||||
the Derivative Works; or, within a display generated by the Derivative Works, if and wherever
|
||||
such third-party notices normally appear. The contents of the NOTICE file are for informational
|
||||
purposes only and do not modify the License. You may add Your own attribution notices within
|
||||
Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the
|
||||
Work, provided that such additional attribution notices cannot be construed as modifying the
|
||||

|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide additional or
|
||||
different license terms and conditions for use, reproduction, or distribution of Your
|
||||
modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and
|
||||
distribution of the Work otherwise complies with the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution
|
||||
intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms
|
||||
and conditions of this License, without any additional terms or conditions. Notwithstanding the
|
||||
above, nothing herein shall supersede or modify the terms of any separate license agreement you
|
||||
may have executed with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade names, trademarks, service
|
||||
marks, or product names of the Licensor, except as required for reasonable and customary use in
|
||||
describing the origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor
|
||||
provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT
|
||||
WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation,
|
||||
any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of permissions under
|
||||
this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory, whether in tort (including
|
||||
negligence), contract, or otherwise, unless required by applicable law (such as deliberate and
|
||||
grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for
|
||||
damages, including any direct, indirect, special, incidental, or consequential damages of any
|
||||
character arising as a result of this License or out of the use or inability to use the Work
|
||||
(including but not limited to damages for loss of goodwill, work stoppage, computer failure or
|
||||
malfunction, or any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works
|
||||
thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty,
|
||||
indemnity, or other liability obligations and/or rights consistent with this License. However, in
|
||||
accepting such obligations, You may act only on Your own behalf and on Your sole responsibility,
|
||||
not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each
|
||||
Contributor harmless for any liability incurred by, or claims asserted against, such Contributor
|
||||
by reason of your accepting any such warranty or additional liability.
|
||||
|
||||

# [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.
