## API
- [run](docs/README.md#run)
## Build
To build a `k6` binary with this extension, first ensure you have the prerequisites:
- [Go toolchain](https://go101.org/article/go-toolchain.html)
- Git
Then:
1. Install `xk6`:
```shell
$ go install go.k6.io/xk6/cmd/xk6@latest
```
2. Build the binary:
```shell
$ xk6 build --with github.com/deejiw/xk6-interpret@latest
```
## Example
```javascript
import { Interpret } from 'k6/x/interpret';
const interpret = new Interpret()
export default function() {
var result = interpret.run(
`package interpret
import "fmt"
// fibonacci is a function that returns
// a function that returns an int.
func fibonacci() func() int {
x, y := 0, 1
return func() int {
x, y = y, x + y
fmt.Println("Calculated:",x)
return x
}
}
func Run(s ...interface{}) interface{} {
f := fibonacci()
var results []int
var i int64
for i = 0; i < s[0].(int64); i++ {
results = append(results,f())
}
return results
}
`,
10
);
console.log(`Results: ${result}`)
}
```
Result output:
```
