Programimi asinkron ka evoluar s\u00eb fundi nj\u00ebsoj si programimi klasik paralel, dhe n\u00eb bot\u00ebn e JavaScript, si n\u00eb shfletues ashtu edhe n\u00eb Node.js, kuptimi i teknikave t\u00eb tij ka marr\u00eb nj\u00eb nga vendet kryesore n\u00eb formimin e mend\u00ebsis\u00eb s\u00eb zhvilluesve. Po ju ofroj nj\u00eb kurs t\u00eb plot\u00eb dhe m\u00eb t\u00eb detajuar me shpjegimin e t\u00eb gjitha metodave t\u00eb zakonshme t\u00eb programimit asinkron, adaptuesve midis tyre dhe hap\u00ebsirave ndihm\u00ebse. Aktualisht, ai p\u00ebrb\u00ebhet nga 23 ligj\u00ebrata, 3 prezantime dhe 28 depo me shum\u00eb shembuj t\u00eb kodit n\u00eb github.

N\u00eb diagram (m\u00eb lart) jan\u00eb treguar lidhjet midis m\u00ebnyrave t\u00eb ndryshme t\u00eb pun\u00ebs me asinkronitetin. Bloket me ngjyra i p\u00ebrkasin programimit asinkron, nd\u00ebrsa ato nj\u00ebngjyr\u00ebshe tregojn\u00eb metodat e programimit paralel (semafor\u00ebt, mutex-\u00ebt, barrierat, etj.) dhe rrjetet Petri, t\u00eb cilat, ashtu si programimi asinkron dhe modeli i aktor\u00ebve, jan\u00eb qasje t\u00eb ndryshme p\u00ebr realizimin e llogaritjeve paralel (ato jan\u00eb dh\u00ebn\u00eb n\u00eb diagram vet\u00ebm p\u00ebr t\u00eb p\u00ebrcaktuar m\u00eb sakt\u00eb vendin e programimit asinkron). Modeli i aktor\u00ebve \u00ebsht\u00eb i lidhur me programimin asinkron sepse realizimi i aktor\u00ebve pa shum\u00ebthithje gjithashtu ka t\u00eb drejt\u00eb t\u00eb ekzistoj\u00eb dhe sh\u00ebrben p\u00ebr strukturimin e kodit asinkron. Linjat piktoreske lidhin ngjarjet dhe radh\u00ebn konkurente me callback-et sepse k\u00ebto abstraksione bazohen n\u00eb callback-e, por p\u00ebrve\u00e7 k\u00ebsaj formojn\u00eb qasje t\u00eb reja cil\u00ebsore.<\/p>\n

N\u00ebn \u00e7do video ka lidhje p\u00ebr repozitor\u00ebt me shembujt e kodit, t\u00eb cil\u00ebt diskutohem n\u00eb video. Kam tentuar t\u00eb tregoj se nuk \u00ebsht\u00eb e nevojshme t\u00eb reduktohet gjith\u00e7ka n\u00eb nj\u00eb abstraksion t\u00eb vet\u00ebm t\u00eb asinkronitetit. Nuk ekziston nj\u00eb qasje universale p\u00ebr asinkronitetin, dhe p\u00ebr \u00e7do rast mund t\u00eb gjenden metodat q\u00eb lejojn\u00eb shkruan kod m\u00eb natyrsh\u00ebm p\u00ebr k\u00ebt\u00eb detyr\u00eb specifike. Sigurisht, ky kurs do t\u00eb kompletohet dhe iu lutem t\u00eb gjith\u00ebve t\u00eb sugjerojn\u00eb tema t\u00eb reja dhe t\u00eb kontribuoni n\u00eb shembujt e kodit. Q\u00ebllimi kryesor i kursit \u00ebsht\u00eb t\u00eb tregoj\u00eb se si t\u00eb nd\u00ebrtohen abstraksionet e asinkronitetit nga brenda, dhe jo vet\u00ebm t\u00eb m\u00ebsojm\u00eb si t\u00eb p\u00ebrdoren ato. Pothuajse t\u00eb gjitha abstraksionet nuk vijn\u00eb nga bibliotekat, por jepen n\u00eb implementimin e tyre m\u00eb t\u00eb thjesht\u00eb dhe shkall\u00eb pas shkalle shqyrtohet funksionimi i tyre.<\/p>\n

Vet\u00ebm p\u00ebrdoruesit e regjistruar mund t\u00eb marrin pjes\u00eb n\u00eb anket\u00eb. Hyni<\/a><\/noindex>, ju lutem.<\/p>\n
