This simple diagram will help you understand the difference between require
and import
.
Apart from that,
You can’t selectively load only the pieces you need with require
but with import
, you can selectively load only the pieces you need, which can save memory.
Loading is synchronous(step by step) for require
on the other hand import
can be asynchronous(without waiting for previous import) so it can perform a little better than require
.
