Module function/ifElse

ifElse

• ifElse<T, F>(condition: Func<boolean>, onTrue: Func<T>, onFalse: Func<F>): Func<T | F>
• ifElse<T>(condition: Func<boolean>, onTrue: Func<T>): <F>(onFalse: Func<F>) => Func<T | F>
• ifElse(condition: Func<boolean>): { <T, F>(onTrue: Func<T>, onFalse: Func<F>): Func<T | F>; <T>(onTrue: Func<T>): <F>(onFalse: Func<F>) => Func<T | F> }

• Creates a function that will process either the onTrue or the onFalse function depending upon the result of the condition predicate.

  example

   const prop = ifElse(
     x => x.a,
     x => x.b,
     x => x.c
   );
   prop({ a: false, c: 2 }); //=> 2
   prop({ a: true, b: 1, c: 2 }); //=> 1
  

  Type parameters

  • T

  • F

  Parameters

  • condition: Func<boolean>

    A predicate function

  • onTrue: Func<T>

    A function to invoke when the condition evaluates to a truthy value.

  • onFalse: Func<F>

    A function to invoke when the condition evaluates to a falsy value.

  Returns Func<T | F>

  A new unary function that will process either the onTrue or the onFalse function depending upon the result of the condition predicate.

• Creates a function that will process either the onTrue or the onFalse function depending upon the result of the condition predicate.

  example

   const prop = ifElse(
     x => x.a,
     x => x.b,
     x => x.c
   );
   prop({ a: false, c: 2 }); //=> 2
   prop({ a: true, b: 1, c: 2 }); //=> 1
