Uncaught TypeError: Cannot read property 'toUpperCase' of undefined

/* if like me, you wanted to declare a function that would return each 
of the letters in a words capitalized seperately and you tried in your
loop: */
for (let k = 0; k <= some_string.length; k++)
// try instead:
for (let k = 0; k <= some_string.length-1; k++)
/* because some_string.length means if the length of your string is, for 
example, 8 - then the last position for the string would be some_string[7]
but in the first for loop, it would loop through some_string[8] as well, 
since the final value of k would be some_string.length = 8 */
