# Loops

```javascript
//Problem:
function formatRecords(input) {
  const lines = input.split("\n");
  let firstLine = true;
  const result = [];
  for (const line of lines) {
    if (firstLine) {
      firstLine = false;
      continue;
    }
    if (line.trim() === "") continue;
    const record = line.split(",");
    if (record[1].trim() === "India") {
      result.push({ city: record[0].trim(), phone: record[2].trim() });
    }
  }
  return result;
}


//**Solution**:
function formatRecords(input) {
  const lines = input.split("\n");

  const result = lines
    .filter(line => line.trim() !== "")
    .map(line => line.split(","))
    .filter(record => record[1].trim() === "India")
    .map(record => ({ city: record[0].trim(), phone: record[2].trim() }));
   
  return result;  
}
```
