# use-strict

Makes all modules in Node get loaded in strict mode.

## Usage

```javascript

require('use-strict')

// That's it, now everything is strict forever.

// in other words: FTFY, YOU'RE WELCOME.

```

## Downside

Strict mode in JavaScript is virtually always a great thing.  It

prevents accidental global leakage, turns silent mistakes into errors,

and removes `with` and `arguments.callee` and their sordid

complexities.  It's mostly a Good Thing.

Unfortunately, it also removes octal literals, which is kind of a

bummer.  You can pass octal strings to Node's functions that deal with

file modes, and they'll do the right thing, so it's not completely

horrible.

The implementation works by patching Node's internal `module.wrapper`

array, and then freezing it, so that further modifications are not

possible.

This means that error printouts that occur on the first line of a node

module will be off by a few characters, since Node does a bit of math

to account for its wrapper script, which will now be off by 13

characters.  This is probably not a big problem, and not really worth

working around.

Also, this means that the *current* module will not be affected.  You

should still `"use strict"` in the module that does

`require('use-strict')`.  This module applies strictness to all

*future* modules loaded by your program.

**Note** You can also run `node --use_strict` and get the same effect

without any of the caveats.
