    Note: Possible gotcha: removing middle characters
    Because trim() trims characters from the beginning and end of a string, it may be confusing when characters are (or are not) removed from the middle. trim(‘abc’, ‘bad’) removes both ‘a’ and ‘b’ because it trims ‘a’ thus moving ‘b’ to the beginning to also be trimmed. So, this is why it “works” whereas trim(‘abc’, ‘b’) seemingly does not. <\/div>\n<\/p><\/div>\n<\/li>\n
