Angular 10 recommends utilizing the "forEach" method in place of "map" since the return value of "map" is not being utilized in this specific context

I encountered the following error message: Consider utilizing "forEach" instead of "map" since the return value is not being utilized in this case. declare const require: { context(path: string, deep?: boolean, filter?: RegExp): { keys(): string[]; (id: string): T; }; };

context.keys().map(context);

Answer №1

It's important to utilize the return value of map(), as pointed out in a few comments.

For more examples and clarity, take a look at these resources: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

Remember that when using map(), the typical syntax is

const a = someArray.map(function)

Don't forget to assign the result of map() to a variable like 'a', instead of just calling it on its own.

This way, you can access the actual value returned by the map() function.
