tryCall

Callable

  • tryCall<T, TResult1, TResult2>(block, onSuccess, onError): Awaitable<TResult1 | TResult2>

  • Returns block().then(onSuccess, onError) when a asynchronous. Else returns try { return onSuccess(block()) } catch (error) { onError(error) } when synchronous

    @example
    const syncBlock = () => 'sync'
    tryCall(syncBlock, (_) => `${_}_foo`);// 'async_foo'
    const asyncBlock = () => Promise.resolve('async')
    tryCall(asyncBlock, (_) => `${_}_foo`);// Promise.resolve('async_foo')
