of a CPU - Pipelining Branch prediction and hardware loop unrolling • Conditional code vs efficiency • Optimizing conditional code • Branchless programming *(v1 - v2) $ • Conditions, or branches: if $ (v > a) $ a = v; Data-dependent code  ## BRANCHES: BANE OF THE PIPELINES • Hard to pipeline code: $ a+=(v1[i]>v2[i])?v1[i]:v2[i] $ load:v1[i]

contexts.| |Indexed Access Types|Using Type\['a'] syntax to access a subset of a type.| |Conditional Types|Create types which act like if statements in the type system.| |Mapped Types|Generating types types, it overlays type analysis on JavaScript's runtime control flow constructs like if/else, conditional ternaries, loops, truthiness checks, etc., which can all affect those types. Within our if check a number of JavaScript libraries, and TypeScript can understand it to narrow types in different branches. In TypeScript, checking against the value returned by `typeof` is a type guard. Because TypeScript

teamScore += 1 } } print(teamScore) // Prints "11" In an if statement, the conditional must be a Boolean expression—this means that code such as if score { ... } is an error, not an clause that sets a different greeting if optionalName is nil. If the optional value is nil, the conditional is false and the code in braces is skipped. Otherwise, the optional value is unwrapped and assigned values whose type is already known. Boolean values are particularly useful when you work with conditional statements such as the if statement: if turnipsAreDelicious { print("Mmm, tasty turnips
