Exemplos de JavaScript

Por que estudar JavaScript? JavaScript é uma das três linguagens que todos os desenvolvedores da Web precisam aprender:

1. HTML para definir o conteúdo de páginas da web

2. CSS para especificar o layout das páginas da web

3. JavaScript para programar o comportamento de páginas da web

Páginas da Web não são o único lugar onde o JavaScript é usado. Muitos programas de desktop e servidor usam JavaScript. O Node.js é o mais conhecido. Alguns bancos de dados, como o MongoDB e o CouchDB, também usam JavaScript como linguagem de programação.

    Interesting post right here. One thing I’d like to say is always that most professional career fields consider the Bachelor Degree just as the entry level standard for an online education. Though Associate College diplomas are a great way to begin, completing your Bachelors opens up many good opportunities to various occupations, there are numerous online Bachelor Course Programs available via institutions like The University of Phoenix, Intercontinental University Online and Kaplan. Another concern is that many brick and mortar institutions make available Online variants of their diplomas but generally for a considerably higher amount of money than the institutions that specialize in online qualification plans.

    I have seen a lot of useful items on your web-site about computers. However, I’ve got the opinion that netbooks are still not nearly powerful adequately to be a good selection if you usually do tasks that require loads of power, just like video editing. But for world-wide-web surfing, word processing, and majority of other prevalent computer functions they are okay, provided you cannot mind small screen size. Thank you sharing your ideas.
