 * Calling a constructor with no arguments should have no parenthesis `'()'`. eg. `var map = new Map;`
 * Put anonymous functions inline if they are not used as a subroutine.
+* Prefer `let` to `var`, unless the variable is not used in a block scoping manner. Be careful when using `let` with `case` switches, as [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/let#Temporal_dead_zone_and_errors_with_let all switch cases share the same block by default].
 * Use arrow functions when possible, unless it makes code less readable. See below for examples.
 * For default parameters, add a space around the default assignment: `function foo(isGood = false)`

 Never use option (1), because it is a special case that only applies when the function has one argument, reducing predictability.
 
-In cases where the return value is used and the expression is a constant ("foo"), a variable (foo), or a member (this.foo), use option (2). Never use braces though, because implicit return only works if there are no braces around the single expression.

 In cases where the expression computes a value (a + 42) or performs a side effect (++a), prefer option (4).
