I’m working on a Node.js application where I receive a response from an API and need to process the data before sending it to the client. I’m wondering if it’s acceptable to use loops (like for or while loops) to iterate over the response data and manipulate it, or if it’s better practice to use the map function provided by JavaScript.
I just want to ensure that i will not block the event loop, so i want to know if it is acceptable to do so.
For example, let’s say I have an array of objects in the response data and I want to extract a specific property from each object and create a new array with just those properties.
Would it be acceptable to do something like this using a loop:
let newData = [];
for (let i = 0; i < responseData.length; i++) {
newData.push(responseData[i].propertyName);
}
Or should I use the map function like this:
let newData = responseData.map(item => item.propertyName);
I want to ensure that my code follows best practices and is efficient. Any insights or advice on this would be greatly appreciated.
