Module function/applyOrReturn

applyOrReturn

• applyOrReturn<T, F>(args: T[], test: F): ReturnType<F>
• applyOrReturn<T, F>(args: T[], test: F extends Function ? ApplyFunc<T> : F): F
• applyOrReturn<T>(args: T[]): <F>(test: F) => ReturnType<F>
• applyOrReturn<T>(args: T[]): <F>(test: F extends Function ? ApplyFunc<T> : F) => F

• If test is function it calls with applied first argument, otherwise just returns test

  example

   applyOrReturn([1,2,3], (...args) => args) //=> [1,2,3]
   applyOrReturn([1,2,3], 'test') //=> 'test'
  

  Type parameters

  • T

  • F: ApplyFunc<T>

  Parameters

  • args: T[]

    Arguments passed to test if it's a function

  • test: F

    if test is function it's called with args

  Returns ReturnType<F>

• If test is function it calls with applied first argument, otherwise just returns test

  example

   applyOrReturn([1,2,3], (...args) => args) //=> [1,2,3]
   applyOrReturn([1,2,3], 'test') //=> 'test'
  

  Type parameters

  • T

  • F

  Parameters

  • args: T[]

    Arguments passed to test if it's a function

  • test: F extends Function ? ApplyFunc<T> : F

    if test is function it's called with args

  Returns F

• If test is function it calls with applied first argument, otherwise just returns test

  example

   applyOrReturn([1,2,3], (...args) => args) //=> [1,2,3]
   applyOrReturn([1,2,3], 'test') //=> 'test'
