# Running JavaScript from the command line
I get quite frustrated running JS by pasting into Chrome/FF and sometimes I like to keep everything local. These are some notes on using Apple's built in intrerpreter, node or phantom.

## Using Apple's built in interpreter

### Create a symlink by putting `jsc` into `/usr/bin`

`sudo ln -s /System/Library/Frameworks/JavaScriptCore.framework/Versions/A/Resources/jsc /usr/bin`

### 1. Use the jsc alias as a REPL

`jsc`

### 2. Run a script using the jsc alias
Create a file and save it. Change to the saved directory and execute the file:

`jsc hello.js`

## Using Node.js

### Install Node using homebrew  

`brew update && brew install node`

### 1. Bring up the REPL: 

`node`

### 2. Run a script: 
Create a file and save it. Change to the saved directory and execute the file:

`node hello.js`

## Using PhantomJS

### Install phantomjs using homebrew

`brew update && brew install phantomjs`

### 1. Bring up the REPL: 

`phantomjs`

### 2. Run a script: 
Create a file and save it. Change to the saved directory and execute the file:

`phantomjs hello.js`
