There is something I don’t really get in programming languages… for example… in Python why do we use .lower() and .upper() to change the text and make it all capital or small, why not just doing that in the string itself… I mean instead of London.upper() why not “LONDON” in the first place???
Variables also confuse me, for example: var myName = "Codey"
var myAge = "19"
console.log("myName " + “myAge”) why cant we just print “Codey 19” string instead…
Thanks in advance!
