Engineering

1. What tech stack do you use? Are you rolling out new technologies or sunsetting older ones? Do you have any legacy system that you need to maintain?
2. What is your maturity stage? Finding a direction, feature work, maintenance...
3. What are the next big engineering challenges you will face?
4. How are requirements delivered to the engineering teams? How are technical decisions made and communicated?
5. What level of involvement do engineers have in relation to architecture and system design? How much freedom for decision making do individual developers have? What happens if an engineer identifies areas of improvement?
6. What is the junior/senior balance of the team?

Parens And Performance

Years ago, some smart folks that worked on JS engines realized that not all JS that's loaded into a page/app initially is needed right away. They implemented JIT to optimize this situation.

JIT means Just-In-Time, which means essentially that the engine can defer processing (parsing, compiling) certain parts of a JS program until a later time, for example when the function in question is actually needed. This deferral means the engine is freer to spend the important cycles right now on the code that's going to run right now. This is a really good thing for JS performance.

Some time later, some JS engine devs realized that they needed to get some hints from the code as to which functions would run right away, and which ones wouldn't. In technical speak, these hints are called heuristics.

So they realized that one very common pattern for knowing that a function was going to run right away is if the first character before the function keyword was a (, because that usually m

1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream
