node-help

node-help is a node module that integrates the standard node REPL with documentation and colors. Our sources currently include the Mozilla Developer Network JavaScript language references for ECMAScript5 and part of the Node api docs for your node version.

Assuming you have Node.js and npm installed on your machine, to install node-help, run the following commands:

• npm install -g node-help
• in your terminal type node-help to start the repl
• Once in the node-help repl, use the help() or i() functions to get help on something you want to know more about.

6description: 
7  Arrays are list-like objects whose prototype has methods to perform  
8  traversal and mutation operations. Neither the length of a JavaScript array  
9  nor the types of its elements are fixed. Since an array's size length grow  
10  or shrink at any time, JavaScript arrays are not guaranteed to be dense. In  
11  general, these are convenient characteristics; but if these features are not  
12  desirable for your particular use, you might consider using typed arrays.   
13  Some people think that you shouldn't use an array as an associative array.  
14  In any case, you can use plain objects instead, although doing so comes with  
15  its own caveats. See the post Lightweight JavaScript dictionaries with  
16  arbitrary keys as an example.
