¿Qué es JavaScript?

JavaScript es un lenguaje de programación interpretado, estándar de ECMAScript. Es un lenguaje de programación orientado a objetos, imperativo, débilmente tipado, dinámico y basado en prototipos. Su sintaxis es similar al lenguaje de programación C.

JavaScript es utilizado principalmente por el lado del cliente, es decir, el lenguaje de los navegadores el cual, permite mejoras en la interfaz de usuario. También es usado en el lado del servidor para páginas web dinámicas.

En la actualidad, todos los navegadores modernos interpretan código de JavaScript integrado en las páginas web. Además, la interacción de JavaScript con la página web se hace a través del DOM (Document Object Model).

Orígenes y evolución de JavaScript

Brendan Eich, un desarrollador de la empresa Netscape tuvo la tarea de crear un nuevo lenguaje de programación en poco tiempo. Su objetivo era que, dicho lenguaje en las páginas web, pudiera aprovechar el procesamiento de los ordenadores para que la navegación en internet fuera más rápida.

Brendan desarrolló un lenguaje al que denominó Mocha el cual, más adelante pasó a llamarse LiveScript. Más adelante, en 1995 se inició un movimiento de márketing que pretendía asociar LiveScript con Java y, gracias a un acuerdo entre Sun Microsystems y Netscape, LiveScript pasó a llamarse JavaScript. Cabe destacar que Java y JavaScript son lenguajes totalmente independientes.

Sin embargo, hasta el año 2004 JavaScript no empezó a despegar siendo el punto clave en su despegue la aparición de una de sus librerías más conocidas jQuery en el año 2006. JQuery pretende llevar a cabo muchas más tareas escribiendo poco código. Desde el 2006 en adelante, JavaScript es uno de los lenguajes más utilizados en desarrollo web.

Características y funcionalidades de JavaScript

El lenguaje JavaScript se utiliza principalmente en el lado del front, lo que ayuda a la interactividad de la web, pudiendo utilizar librerías y frameworks como angular, backbone o react. De igual forma, JavaScript se puede utilizar en los servidores web gracias a entornos como NodeJS.

Estas son algunas de las características y funcionalidades que presenta JavaScript:

Es ligero.
Es multiplataforma. Puede ser usado en Windows, Linux, Mac o en cualquier navegador.
Es estructurado e imperativo.
Es orientado a objetos y eventos.
Es interpretado.

¿Qué es la tecnología?

La tecnología es sólo una herramienta.
En términos de llevar a los niños a trabajar juntos y motivarlos, el profesor es el más importante.

Bill Gates

Especialmente en la tecnología, necesitamos cambios revolucionarios, no cambios incrementales.
