good stuff thanks đź‘Ť
could you please give me advice, on the reason why we use Buffer.from to convert STRING to Buffer?
Thanks! I had the same idea of using Buffer but I wasn't sure about the S3 configuration to store it as JSON.
Cheers mate :)

Buffer.fromto convert STRING to Buffer?
Basically, as I understand it, to transfer data across the internet (in this case, the content of a file) it needs to be represented as chunks of binary information that can be segmented and indexed while the transfer is undergoing. A simple string would not do the trick since its representation –while at a machine level can be read as binary– is not formatted correctly, I think it is technically just a pointer to a memory range where it is stored. The Buffer here actually creates –or rather, replicates– the binary information that represents the content of the string variable and makes it available as a variable itself.
thank you
Thanks brother
Thanks, I was looking for Buffer.from ... :)
