Javascript The Fascinating Parts
summary
Argues to stop using var and use const where possible, falling back to let; shows const prevents rebinding but not internal mutation (objects remain mutable). Replaces arguments (not an array) with the rest parameter which is an array, and uses the spread operator to call and concatenate arrays. Demonstrates reduce with arrow functions, template literals, object shorthand and destructuring, for...of with entries to get index and value, default parameter expressions, and warns that arrow functions change scoping of this and arguments, unlike regular functions.
