OpenSource For You - - DEVELOPERS OVERVIEW -

Asyn­chro­nous gavaScript and uML (AgAu) is not a lan­guage or new tech­nol­ogy, but a com­bi­na­tion of known tech­nolo­gies such as HTML, uML and gavaScript. It has been com­bined to serve users in a bet­ter and faster way. Be­ing asyn­chro­nous is the key; all user ac­tions are han­dled in par­al­lel. In tra­di­tional Web ap­pli­ca­tions, all user ac­tions were han­dled se­quen­tially. AgAu re­quires HTML for cre­at­ing and load­ing pages, gavaScript for al­ter­ing page con­tent, uMLLgSlN for data com­mu­ni­ca­tion, and server­side busi­ness logic. AgAu-based Web ap­pli­ca­tions re­duce un­nec­es­sary server calls and the reload­ing of the en­tire page for small user re­quests or ac­tions. • GWT pro­vides a com­piler, which con­verts all code writ­ten in gava into gavaScript. Be­cause of this, de­vel­op­ing ap­pli­ca­tions with cross-browser com­pat­i­bil­ity be­comes eas­ier. It has a way of main­tain­ing a his­tory of ac­cessed ap­pli­ca­tion rRLs, let­ting you use the browser’s cor­ward/_ack but­ton. ae­bug­ging of client-side code is pos­si­ble. Since we are de­vel­op­ing in gava, de­bug­ging the AgAu ap­pli­ca­tion is pos­si­ble dur­ing devel­op­ment, us­ing a na­tive Iab.
