# quick format

Solves a problem with util.format in <= Node 5.9

## usage

```js
var format = require('quick-format')
format(['hello %s %j %d', 'world', {obj: true}, 4, {another: 'obj'}])
```

##  util.format

In `util.format` for Node 5.9, performance is significantly affected
when we pass in more arguments than interpolation characters, e.g

```js
util.format('hello %s %j %d', 'world', {obj: true}, 4, {another: 'obj'})
```

This is mostly due to the use of `util.inspect`. Use `JSON.stringify`
(safely) instead which is significantly faster. 

It also takes an array instead of arguments, which helps us 
avoid the use of `apply` in some cases.

Also - for speed purposes, we ignore symbol.

## Benchmarks

Benchmarks are very marginally slower than 5.9 util.format when
there is no "tail" arguments, 

```
util*50000: 112.749ms
quick*50000: 118.393ms
utilWithTailObj*50000: 517.232ms
quickWithTailObj*50000: 141.821ms
util*50000: 111.217ms
quick*50000: 117.432ms
utilWithTailObj*50000: 504.271ms
quickWithTailObj*50000: 142.759ms
```
