None of the string methods modify this – they always return fresh strings.
charAt(pos: number): string ES1
Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).
Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.
Switch to the master branch and make sure you are up to date:

Command-line arguments in Python show up in sys.argv as a list of strings (so you'll need to import the sys module).
For example, if you want to print all passed command-line arguments:
import sys
print(sys.argv) # Note the first argument is always the script filename.Command-line options are sometimes passed by position (e.g. myprogram foo bar) and sometimes by using a "-name value" pair (e.g. myprogram -a foo -b bar).
