Node.js/NestJS – How should we use await statements inside the Foreach loop

Looping is a language used to execute a statement or a set of statements multiple numbers of times, depending on the result of the condition to be evaluated. The foreach loop is used when you want to iterate over the elements of the collection. The best part of using the foreach loop is, it executes for each element present in the array.

The foreach loop makes the code simpler by maintaining no explicit counter, which is not found in other for loop constructs. Foreach loop says – do this to everything in this set”, rather than “do this x times.”

Description of the Issue:-

I was working in an API with Node.js and NestJS. I encountered this issue in the execution of await statements. When I tried using the Foreach loop inside the async function, I was not able to execute await statements.

The Solution Offered:-

I tried all the possible ways to sort this execution error but couldn’t figure out why it was not working. So, I decided to use the async word inside the Foreach loop before looping the element. Below is how I tried and succeeded.

array.forEach( async element =>{})

Fortunately, it worked for me and I was able to execute await statements without any errors.
