Module iterable/find

find

• find<T, R>(predicate: (t: T) => t is R, iterable: Iterable<T>): T
• find<T>(predicate: (t: T) => boolean, iterable: Iterable<T>): T
• find<T, R>(predicate: (t: T) => t is R): (iterable: Iterable<T>) => T
• find<T>(predicate: (t: T) => boolean): (iterable: Iterable<T>) => T

• Find element in iterable sort matched with predicate

  example

   find(n => n % 2 === 0, new Set([1, 2, 3, 4]));    //=> 2
   find(n => n > 100, new Set([1, 2, 3, 4]));        //=> undefined
