## Description
<section id='description'>
Перечислив первые шесть простых чисел: 2, 3, 5, 7, 11 и 13, мы увидим, что 6-е число равно 13. Что такое <code>n</code> е простое число?

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>nthPrime(6)</code> should return 13.
    testString: assert.strictEqual(nthPrime(6), 13);
  - text: <code>nthPrime(10)</code> should return 29.
    testString: assert.strictEqual(nthPrime(10), 29);
  - text: <code>nthPrime(100)</code> should return 541.
    testString: assert.strictEqual(nthPrime(100), 541);
  - text: <code>nthPrime(1000)</code> should return 7919.
    testString: assert.strictEqual(nthPrime(1000), 7919);
  - text: <code>nthPrime(10001)</code> should return 104743.
    testString: assert.strictEqual(nthPrime(10001), 104743);

## Solution

```js
const nthPrime = (number)=>{
 let pN = 2;
 let step = 0;
 while (step<number) {
   let isPrime = true;
   for(let i = 2;i<pN;i++){
      if(!(pN%i)){
        isPrime = false;
        break;
      }
   }
   isPrime ? step++ : '';
    pN++;
 }
 return pN-1;
}
```
