Array.prototype.map()

last modified: 22 July, 2020

Javascript tiene funciones extraordinarias que hacen cosas asombrosas con pocas líneas de código. La función map(), es una de ellas. Vamos a dar un repaso a una serie de ejemplos que nos permitirán conocer un poco mas a fondo esta función.

Para no perder la costumbre comenzaré con la definición de la documentación oficial, la cual expone lo siguiente:

El método map() crea un nuevo array con los resultados de la llamada a la función indicada aplicados a cada uno de sus elementos.

Una gran ventaja de usar map() en ReactJS radica en que el resultado de las operaciones no realiza ningún tipo de mutación en el array original, el cual es un concepto muy utilizado en el desarrollo con ReactJS, map() retorna un nuevo array con los resultados esperados, lo cual se ajusta perfectamente a la filosofía del framework creado por Facebook.

Rethinking technical writing. Can Poet provide a better experience?

last modified: 4 February, 2019

Being a blogger for so long (roughly ten years) and having written three books I started questioning the process of writing and later reading technical materials. It looks like there is a lot of room for improvements. Especially those materials that involve JavaScript, HTML and CSS and usually have code mixed with text. This article summarizes my thoughts and it is a gentle introduction to Poet - a platform that I recently lunched.
