There are many methods, and the following is just one of them.

    function toUpperCaseFirstLetter(str) {
      if (typeof str !== 'string' || str.length === 0) {
        return str;
      }

      return str[0].toUpperCase() + str.slice(1).toLowerCase();
    }

    // some tests
    expect(toUpperCaseFirstLetter('abc')).eql('Abc');
    expect(toUpperCaseFirstLetter('ABC')).eql('Abc');
    expect(toUpperCaseFirstLetter('')).eql('');
    // other tests....
