Testing of JS async/await
loop performance with for loop await vs map await.
Since for loop await
is a common mistake that JS developers makes, causes major performance issues without understanding the concept of parallel execution which can be done with Promise.all()
.
Can copy all this and execute to clone & install
git clone https://github.com/ChrisLegaxy/js-async-await-parallel-execution.git \
&& cd js-async-await-parallel-execution \
&& yarn
To run tests, run the following command
yarn test
