// A means of using underscore.js to do templates with conditionals
// Inside of underscore's template, it returns a function that uses
// 'with' on a variable named obj, and you can touch into that using
// inline JS and <% %> wrappers

// A template with conditional display of last names:
var good = _.template("Hello: <%= name %> <% if (obj.lastname) { %> <%= lastname %> <% } %>");

// A template that tries to do that, but fails:
var bad = _.template("Hello: <%= name %> <% if (lastname) { %> <%= lastname %> <% } %>");

# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run

Implementation notes on react's scheduling model as of (shortly before) 16.8.0

While the public API intended for users to use is the scheduler package, the reconciler currently does not use scheduler's priority classes internally.

ReactFiberScheduler has its own internal "mini-scheduler" that uses the scheduler package indirectly for its deadline-capable scheduleCallback.

This is kind of a documentation of implementation details that I suppose will be gone by the end of the year, but what can you do.
