java script introduzione (italiano)

Forse già sai che javascript è uno dei più popolari linguaggi di scripting e funziona con la maggior parte dei browser, è usato per rendere le pagine HTML interattive ed è integrato in esso spesso, esso non è java poichè rientra nella categoria di programmi come C o C++ bensì è simile al PHP come utilità in generale intendo

Se conosci l'HTML è meglio però puoi imparare il javascript senza questa conoscenza anche se può risultare più difficile, useremo un metodo per impararlo intuitivamente usando la logica
per introdurre javascript all'interno di HTML dovrai scrivere in questo modo

* here you write the javascript code=qui scrivi il codice javascript

in seguito vedremo il comando "id" associato al javascript
adesso invece vediamo come scrivere un paragrafo utilizzando javascript invece di HTML

*here you write whatever you want=qui scrivi quello che vuoi

Ora vedremo una funzione e come usare "id"
inoltre vedremo come creare un bottone
prima di tutto chiamiamo la funzione tramite la key "function" usando un nome qualsiasi come asdfgh e scriviamo come lavora questa funzione, poi scriviamo un paragrafo assegnando l'id e alla fine creiamo il bottone

**you've changed what you wrote=hai cambiato quello che avevi scritto
*click here to change what you wrote=clicca qui per cambiare quello che hai scritto
*here you change=qui cambia la scritta

ecco il video 

grazie e a presto :)
