Rewards for the best answer from the 4th quarter of 2016

Question

Inspired by the mods of a few other communities, I would like to start quarterly rewards for the best answer, and I'd ask the community for the best answers from the past quarter to get an additional reward:

Please link to an answer which was created from October 1st 2016 through December 31st 2016 and which you think deserves an additional reward. Only one entry per answer will be valid. For multiple favorites submit separate answers to this post.

Here is a data query to help with the decision making process:

• Answers with most votes from 4th quarter of 2016

Otherwise you can choose your own favorite answer which didn't get the limelight. Answer can be from you or from someone else.

The highest voted answer of this meta post will be picked up for the reward of 200 points after 2 weeks.

Note: Answer must have 1+ upvote and submitted in the same quarter only. Answer should not be a wiki. Please only propose one post in any answer here so the votes can easily be tallied.

Answer 1

Eric's answer on What is suggested approach to transfer VF pages to be lightning ready is creative, novel, and looks like something I will imitate in the future. He freely provided a template that will help ease the transition to SLDS.

Answer 2

I would like to nominate another answer by Eric on How to convert a Visualforce apex:pageMessages to be lightning style. It inspired me to write a component that can add an arbitrary number of page messages as toasts, which I intend to share there when I get a chance.

Answer 3

I would like to nominate an answer by Mohith on How does component.set works underneath the hood . It cleared explained how lightning component works underneath the hood.

Answer 4

I would like to nominate this answer by sfdcfox:

Help on Invokable Apex Test class and @Future callout Apex test Class

It was one of the most fundamentally helpful posts I have seen (for me at least) it is so simple and yet changed the way I think about mocks.

No more needlessly checking endpoints, setting values, having huge class to test callouts. Seems so obvious yet the SF examples led me in the opposite direction

Thanks @sfdcfox

Answer 5

I'd like to add another one here that I found interesting: Dan Wooding's answer on remove advertising on login page of Salesforce. Pretty interesting question that I had often wondered myself. I especially like the recommendation to use https://blank.org/ as a replacement url.

Answer 6

Ok, finally getting around to some nominations.

This nomination is from How to avoid instantiating object inside a loop?

Adrian's answer was initially quite short, but was updated to include some benchmarks. To me, this is the type of answer that goes the extra mile.

This answer caters to beginners and those just looking for some quick information (concise recommendation with an easily understandable example).

It also caters to experts and detail-oriented devs. We all know (or at least I hope we all know) that premature optimization is the root of all evil. Getting some hard data that validates the original claims of the answer is good, but knowing how much of a difference setting fields using dot-notation vs using the sObject constructor makes is vital to making informed decisions.
