Base64 Encoding/Decoding explained

very well explanation. Thank you

great for optimizing/taking advantage of funtions in the language, not so much for the actual learning :/

"new Buffer" has been depricated since Node v6. Just use this:
const newEncoded = Buffer
.from(input[, initialEncoding])
.toString(newEncoding);

Also, the "=" at the end is important if you need to concatenate base64 strings.

The use of "=" in the binary format doesn't make sense. It has to be padded with zeros "0". Your map of "1111=" to 60 proves this as it is actuall a map of "111100" to 60.

Fun fact:
Base64 encoding is a secondary kind of encoding relative to ASCII, since you pad (first with zeros, then with "=" symbols) to get base64, but to go back you need to trim (first trimming "=" then trimming zeros). You can't reverse their roles in this regard since the base64 character set is a subset of the ASCII character set.

You are a genius, I've been sucking with this about 2 days ago, and ur video brightened my mind THANKS!

Absolutely Amazing

And another one that skips the binary etc
Why because you do not know it

What if there is a space between the words? like- "Hello There"
I tried it but it is wrong starting the second word, so I am guessing the space has something to do with it? Yelp!

Thank you totally got it

Sublime. Thanks

something is not adding here - 1111 cannot be 60 in decimal 2^3 + 2^2 + 2^1 + 2^0 = 8 + 4 + 2 + 1 = 15

I got what i wanted from minute 5 but i watch the whole thing just for the good way of explaining the subject. Thank you very much my man.

Thanks a lot for the explication. Can you please tell me why you have to make groups of 6 bits?

does a frontend dev convert image to base64 and the backend guy save it as string using LOB?

nice job

Nice explanation!

Can I use it for html

I have something I need decoded that's in base 64. I'm just learning, but it's important!

😄

For the past 5 hrs I've been searching for I dont know what but your video solved my problem, you are god's angel bro 😭😂

how to do this in angular typescript

What's the name of that VSCode theme?

Very nice, thank you!
