How can I use advanced array mapping in JavaScript?

You can use methods like map(), filter(), and reduce() to manipulate arrays effectively. What specific use case do you have in mind?

I want to transform an array of objects to only include certain properties.

You can achieve that using map(). For example, if you have an array of objects, you can do something like this: array.map(obj => ({ prop1: obj.prop1, prop2: obj.prop2 })). What properties are you looking to include?

I need to include 'name' and 'age' from each object.

You would write: array.map(obj => ({ name: obj.name, age: obj.age })). This will create a new array with only the 'name' and 'age' properties.

Can I also filter the array at the same time?

Yes, you can chain filter() with map(). For example: array.filter(obj => obj.age > 18).map(obj => ({ name: obj.name, age: obj.age })).
