WebAssembly cambia la regole

0:00:06.096,0:00:08.555
rendendo le perfomance delle applicazioni native

0:00:08.555,0:00:11.099
assolutamente sicure,

0:00:11.099,0:00:12.655
pur garantendo la piena funzionalità

0:00:12.655,0:00:16.289
dei giochi, delle principali applicazioni,

0:00:16.289,0:00:18.994
di un software in un computer,

0:00:18.994,0:00:21.966
WebAssembly ha soprattutto uno scopo:

0:00:21.966,0:00:24.021
se sul web abbiamo JavaScript,

0:00:24.021,0:00:25.214
un ottimo linguaggio,

0:00:25.214,0:00:28.057
tuttavia non è abbastanza veloce

0:00:28.057,0:00:30.304
per avviare un'applicazione ampia.

0:00:30.304,0:00:32.000
WebAssembly ha un formato binario,

0:00:32.000,0:00:34.033
è compatto al download,

0:00:34.033,0:00:37.016
con compilazione ed esecuzione effcienti.

0:00:37.016,0:00:40.674
WebAssembly rappresenta un passo avanti

0:00:40.674,0:00:42.302
perché velocizza l'avvio.

0:00:42.302,0:00:45.500
Alcune app sono doppiamente veloci

0:00:45.500,0:00:47.612
e ci sono ancora altre ottimizzazioni

0:00:47.612,0:00:48.956
a portare un'evoluzione

0:00:48.956,0:00:51.133
velocizzando l'avvio di grandi app

0:00:51.133,0:00:52.646
anche sui telefoni cellulari.

0:00:52.646,0:00:56.094
E ne otterremo enormi benefici

0:00:56.094,0:00:57.375
nonché un gran rendimento.

0:00:57.375,0:00:59.700
Una volta completato, il codice sarà più veloce

0:00:59.700,0:01:03.508
WebAssemply migliora le alte prestazioni

0:01:03.508,0:01:06.236
senza l'inserimento di plugin.

0:01:06.236,0:01:08.976
Con WebAssembly possiamo avere

0:01:08.976,0:01:11.559
veri dati int64.

0:01:12.891,0:01:17.336
E più controllo sulla gestione della memoria

0:01:17.336,0:01:18.995
quello che non potevamo prima.

0:01:18.995,0:01:21.225
Ci sarà un performance più liscia

0:01:21.225,0:01:22.904
per tutto il tempo di uso dell'app

0:01:22.904,0:01:25.180
senza i soliti balbettii e interruzioni

0:01:25.180,0:01:29.347
grazie ad un diverso JIT o diverso

0:01:31.160,0:01:34.042
Ora qualsiasi sviluppatore

0:01:34.042,0:01:38.209
può portare le sue applicazioni C

0:01:39.151,0:01:41.879
o C++ sul web con un'ottima performance

0:01:41.879,0:01:44.004
e con tutte le funzioni connesse

0:01:44.004,0:01:47.572
in modalità nativa su Windows, Mac o

0:01:47.572,0:01:49.846
un browser, una cosa rivoluzionaria:

0:01:49.846,0:01:51.738
l'utente va sulla pagina web

0:01:51.738,0:01:53.120
ed iniziare ad usare l'app.

0:01:53.120,0:01:55.616
Niente download, installazione o rischi.

0:01:55.616,0:01:57.740
E' un approccio rivoluzionario.

0:01:57.740,0:02:01.281
Cliccando sull'URL si ha una scena gigante

0:02:01.281,0:02:05.414
e ci si immerge nell'esperienza

0:02:05.414,0:02:08.112
vicini alla propria performance nativa,

0:02:08.112,0:02:11.507
ma utilizzabile su browser ovunque.

0:02:11.507,0:02:13.734
E' incredibile.

0:02:13.734,0:02:15.911
Scrivere un codice in una lingua

0:02:15.911,0:02:17.873
e poi passarlo alle varie piattaforme,

0:02:17.873,0:02:20.950
questi i grandi vantaggi ingegneristici.l
