javascript - Node.js errors fail silently -


i jumping onto node.js project errors fail silently , app doesn't throw errors unless put in try..catch block. example:

console.log(ok) // doesn't throw errors during runtime; api fails silently.

try {   console.log(ok) } catch(e) {   console.log(e)// throws referenceerror: ok not defined }

does know why might be?

thank in advance!

does know why might be?

clearly, code in containing scope catching , suppressing errors. unfortunate, common, practice.

sadly you'll have root out code, there's no real shortcut. run --inspect (on recent versions of node) , tell debugger stop on all exceptions, caught ones, may track them down some. it's going tedious, i'm afraid.

one possible further thought: on only-slightly-older versions of node, unhandled promise rejections not reported. if code inside (say) promise executor (the function pass new promise) or then or catch handler (or async function), throw being converted promise rejection. latest versions of node report unhandled promise rejections. (in not-distant-future, they'll terminate node process.)

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
