Relearned that strings are immutable in JS, learned about Unicode a bit and that you can include it in variable names but not to trust if it’s normalized, learned about different bases 0o octet 0b binary 0x hexadecimal, and about the BigInt object introduced in 2020 to handle base 64 numbers.

Learned some things about text and that some characters are two sixteen bit values, such that a string with a heart would have a length of two whereas a string with the euro character is just a sixteen bit character. Also learned about some string normalization methods that I’d like to play with as well as a quick intro to Symbols which I need to dive deeper I to. There was also some good advice on when to use null
