# first method

String first([

1. int count = 1

])

Returns the first `count` characters of the string. If `count` exceeds the string length, it returns the whole string. If the string is empty or null, it returns an empty string.

## Implementation

    String first([int count = 1]) {
      if (isEmpty || count.isLtOrEt(0)) return '';

      return length.isLtOrEt(count) ? this : substring(0, count);
    }
