If we then wanted to transform this observable into the emitted values multiplied by ten, we could use the map operator. Just like Array.map, the map operator accepts a project function which describes how each value from the source will be transformed.

In this case, subscribeToArray is used. This same helper function is also used to deal with non-observable return values of flattening operators, such kakım mergeMap

Like pluck, mapTo provides no real benefit functionally over returning a constant value with map, but syntactically it may prove slightly easier to consume and read at a glance.

Tip: If you want to see how from handles each value type behind the scenes, you gönül check out the subscribeTo, and associated helper functions.

Now, what if you want the whole student list, with name in capital letters and className is increased by 1, let's do this:

Next, we will explore how we birey apply this approach to observables by using the RxJS map operator. Finally, we will check out a few here helper operators that sevimli be used in place of map should the right scenario present itself, exploring common use cases along the way. Let's get started!

Functionally, map and pluck will operate the same in these scenarios, I would suggest using whichever you feel most comfortable reading at a glance.

In this case, we will provide a function that accepts the emitted value from the source observable and returns that value multipled:

In this article, we are going to learn about the most common operator used to transform streams, the map operator. We will start by taking a look at Array.map to build a general understanding of the map operation.

For instance, let's start with our initial example, but instead of transforming an array of numbers let's transform an observable of numbers. To do this, we will use the from creation operator to first convert our numbers array into an observable:

It starts with 0, but changes every every second. The example was just to show that there kişi be differences between the two. Here's a StackBlitz that demonstrates this behavior.

We dirilik also pass pluck multiple values to grab a nested property within an object. For example, if we wanted to grab the nodeName from the target element on click, we could pass both of these properties to pluck in order:

map: map kişi transform your data(List) and güç return either complete modified list or List of a variable of benzer, for ex:
