Good 👍

In the chart at 3:48 -- lindex, lrange, linsert, lreplace: at very least we should say 'characters' instead of 'character', to avoid confusion with a type of a single character, which Tcl does not have (they are just strings of 1 char) but so many other languages do. Probably isn't it better to just put the word 'string' in the description instead of 'character'? Nice video, just mentioning for people who work in many languages, a char is almost more like an int than a string to them. Also, various string subcommands actually DO return or take a character, which happens to be a string of length 1 because that is how tcl handles single chars.

Some other things if this is the main way some people are learning the Tcl string commands. What you show for 'string match' you can actually get from 'string equal' cheaper: string equal ?-nocase? ?-length length? string1 string2 Even there, we have extra power, you can only look at the first length chars for the comparison, and you can decide whether to wOrRy aBOuT cAse or not. 'string match' in Tcl is even more powerful than that, tho, for fancier things you can use regex, but this is very easy to learn, remember and use: See if pattern matches string; return 1 if it does, 0 if it does not. If -nocase is specified, then the pattern attempts to match against the string in a case insensitive manner. For the two strings to match, their contents must be identical except that the following special sequences may appear in pattern: * Matches any sequence of characters in string, including a null string. ? Matches any single character in string. [chars] Matches any character in the set given by chars. If a sequence of the form x-y appears in chars, then any character between x and y, inclusive, will match. When used with -nocase, the end points of the range are converted to lower case first. Whereas {[A-z]} matches “_” when matching case-sensitively (since “_” falls between the “Z” and “a”), with -nocase this is considered like {[A-Za-z]} (and probably what was meant in the first place). \x Matches the single character x. This provides a way of avoiding the special interpretation of the characters *?[]\ in pattern.

This is pretty minor, but could confuse beginners. Tcl is case sensitive, so only "string" is recognized, not "String". So, when we cut-and-paste a command and PowerPoint or Word or whatever Capitalizes the s to 'String' that might confuse beginners if they type it that way. I am often in my day going back and correcting improper Capitals to Lowercase by hand, so I guess 'string tolower $myString' is pretty useful.

Very good. The trim, trimright, trimleft can remove any number of different chars from your string, not just a single particular one. The value you pass it is a string, but any character found in it will be removed.

very helpful, thanks very much!
