perf-table
Compare the performance of functions.

}
// Table is a promise that resolve when done printing/writing the table.
// Resolves with formatted table
const data = await table([
['for', forLoop],
['for of', forOf],
['while', whileLoop],
['forEach', forEach]
]);
```
OUTPUT:

### Providing Tuples with other configuration
If you want to configure the table further you will have to put the array demonstrated above in the `compare` key of your options.
```js
table({
compare: [
['for', forLoop],
['for of', forOf],
['while', whileLoop],
['forEach', forEach]
],
...
});
```
### Benchmark Options
`perf-table` is on top of [benchmark.js](https://benchmarkjs.com) and you can configure the each comparison run with [benchmark.js options](https://benchmarkjs.com/docs#options).
```js
table({
compare: [ ... ],
options: {
minSamples: 500
}
});
```
### Output Modes
`perf-table` comes with a few output modes pre configured.
- cli (default) - output a table formatted for the CLI
- md - output a markdown table
- html - output a html table
- csv - output the table data in csv
```js
table({
compare: [ ... ],
renderer: 'html'
})
```
### Custom Renderer
If you want to control how the table renders, pass a function to `renderer` and this will be used to render the perf table data.
```js
const renderCSV: IRenderFunction = data =>
data.reduce((text, line) => text + `\n${line.join(',')}`, '');
table({
compare: [ ... ],
renderer: renderCSV
})
```
### Writing to a file
By default `perf-table` just prints the table to the console. If you provide a file path in the `file` option the table output will be written to that path.
```js
table({
compare: [ ... ],
file: 'test.txt'
})
```
### Force Logging
When the `file` option is provided the table will not be logged to the console. To override this behavior also pass `log: true`.
```js
table({
compare: [ ... ],
file: 'test.txt',
log: true
})
```
### BundlePhobia Stats
You can display [bundlePhobia](https://bundlephobia.com/) column with your perf table to really compare yourself against the competition.
```js
table({
compare: [ ... ],
bundle: true
})
```
#### Link
To add a link the to [bundlePhobia](https://bundlephobia.com/) output set `bundle` to `'link'`.
```js
table({
compare: [ ... ],
bundle: 'link'
})
```
