  •  
  • // Accessing individual values
  • alert(nameArr[0]); // Outputs: Harry
  • alert(nameArr[1]); // Outputs: John
  • alert(nameArr[nameArr.length - 1]); // Outputs: Alice
  •  
  • var str = 'Hello World!';
  • var chars = str.split('');
  • console.log();
  •  
  • // Accessing individual values
