Fa'idodin TypeScript
Samfurin TypeScript yana ba da fa'idodi masu yawa akan daidaitaccen JavaScript. Ta hanyar kunna nau'ikan madaidaici, TypeScript yana rage yuwuwar kurakurai na lokacin aiki, yana mai da gyara kuskuren ƙarancin gogewa mai raɗaɗi. Bugu da ƙari, yana samar da ci gaba ta atomatik kammalawa, kewayawa, da sake fasalin, yana sa shirye-shiryen ya fi ƙarfi da inganci.
TypeScript yana ba da ra'ayi na "JavaScript na gaba," yana ba masu haɓaka damar amfani da fasalulluka na JavaScript na gaba waɗanda injunan JavaScript ba su da tallafi a halin yanzu. Yana sa TypeScript ya zama mai tallata sabbin abubuwan JavaScript, yana tabbatar da masu haɓakawa ba sa buƙatar jira don aiki da amfani da sabbin abubuwa.
