Hordhac: Maxay tahay TypeScript?
JavaScript waa luuqadda rasmiga ah ee mareegaha (Web-ka), laakiin marka ay mashaariicdu weynaadaan, waxa soo baxa caqabado dhanka maaraynta koodhka ah. TypeScript, oo ay Microsoft samaysay, waa 'superset' ka dhisan JavaScript kaas oo ku daraya nidaamka noocyada (Static Typing). Maanta, ku dhowaad shirkad kasta oo tech ah waxay koodhkeeda u beddelaysaa TypeScript.
1. Qabashada Khaladaadka xilliga Development-ka
Mid ka mid ah dhibaatooyinka ugu weyn ee JavaScript waa in khaladku uusan soo bixin ilaa barnaamijku uu 'Run' ka noqdo (Runtime). TypeScript waxay kuu ogolaanaysaa inaad khalaadka aragto adigoo weli koodhka qoraya. Tusaale ahaan, haddii aad isku daydo inaad isku darto lambar iyo qoraal si aan loogu talagalin, TypeScript ayaa ku xasuusinaysa.
// JavaScript (Error-ku wuxuu soo baxayaa runtime) function dhibco(a, b) { return a + b;}// TypeScript (Error-ku wuxuu soo baxayaa isla markiiba)function dhibco(a: number, b: number): number { return a + b;}
2. IntelliSense iyo Autocomplete ka wanaagsan
Sababta ay dad badani u jecelyihiin TypeScript waa 'Developer Experience' (DX). Markaad isticmaalayso IDE sida VS Code, TypeScript waxay ku siinaysaa autocomplete aad u sax ah. Waxaad si fudud u garan kartaa 'properties' ka ay leedahay Object kasta adigoon dib ugu laaban faylalkii hore ee aad qortay.
3. Readability iyo Maintenance (Koodh la fahmi karo)
Markaad ku dhex jirto koox horumariyayaal ah (Team), TypeScript waxay u adeegtaa sidii 'documentation' ahaan. Markaad aragto interface ama nooca xogta (Type), waxaad si fudud u fahmaysaa waxa koodhkaas loogu talagalay. Tani waxay sahlaysaa in mashaariicda waaweyn la dayactiro (Maintain) muddo dheer.
interface User { id: number; username: string; email: string;}const newUser: User = { id: 1, username: "hobaydi_dev", email: "dev@hobaydi.com"};
4. Taageerada Features-ka Cusub
TypeScript waxay kuu ogolaanaysaa inaad isticmaasho muuqaalada ugu dambeeyay ee JavaScript (ES6+ features) xitaa haddii browserradu aysan weli wada taageerin. Waxay koodhkaaga u beddelaysaa (Transpile) nooc hore oo JavaScript ah oo browser kasta uu fahmi karo.
