// *** map ***
const inc = (i:number) => i+1;

u.map(inc, [1,2,3]); // $ExpectType number[]
u.map(inc, ["potato"]); // $ExpectType number[]
u.map({a:1},{a:2});  // $ExpectType Mapped<{ a: number; }, { a: number; }>

u.omit('bar', { }); // $ExpectType object
u.omit(['bar'], { }); // $ExpectType object

u.omitBy([ 'banana' ], { } ); // $ExpectError

// *** constant ***

// $ExpectType { banana: number; }
u.constant({ banana: 1 })('foo');

/// *** freeze ***

// $ExpectType { potato: number; }
u.freeze({ potato: 1 });
