Let’s see the unique value for the income target variable and see the distribution of income:df[‘income’].value_counts() The result is as follows: Figure 1.19 – Distribution of income As shown in the results, there are 24,720 observations with an income greater than $50K and 7,841 observations with an income of less than $50K. In the real […]
In this section, we are going to explore each variable separately. We are going to summarize the data for each feature and analyze the pattern present in it. Univariate analysis is an analysis using individual features. We will also perform a bivariate analysis later in this section. Univariate analysis Now, let us do a univariate […]
In this section, we will derive the summary statistics for numerical columns. Before generating summary statistics, we will identify the categorical columns and numerical columns in the dataset. Then, we will calculate the summary statistics for all numerical columns. We will also calculate the mean value of each numerical column for the target class. Summary […]
In the preceding code block, we created the exerciseList signal by declaring it to contain ExerciseSetList and initializing it with an empty list. Then, we changed the getInitialList method toupdate the exerciseList signal based on the API return. We also changed the delete method to update the signal after deleting the diary entry. As we […]
As frontend developers, we need to worry about the technical performance of our applications. Small UI details, such as the loading screen that we created in Chapter 8, Improving Backend Integrations: the Interceptor Pattern, improve our users’ perception of the application’s performance. One of these UI details is the transition between pages of our application. […]
The main intention behind the new HTML template flow control syntax was to have a new basis for building new possibilities in the framework’s templates. The first new feature made possible by the syntax is the defer instruction, with which it is possible to lazy load components directly from the HTML template. We learned in […]
Since version 2 of the framework, the HTML template syntax has remained relatively stable and without much evolution. By using custom properties, we can evaluate conditions and iterate over lists and other forms of flow control to create visualization logic in components. The *ngIf, *ngFor, and *ngSwitch directives are used to improve the developer experience, […]
With the Docker image we created, we can run our project on any cloud provider that offers container services. However, there are other ways to deploy our Angular project. One of these alternatives is Azure Static Web Apps, a service that specializes in web page design and allows automatic integration with GitHub. Let’s see it […]
The environmental needs of a frontend application running in production are different from the development environment we have seen so far in the book. When we are developing, we look for speed in compilation, powerful debugging, and profiling tools to analyze our code, as well as generating boilerplate code, among other features. Even though it […]
After finishing the task of deploying our backend, we need to change our frontend project to make requests to our cloud infrastructure. But here, a problem arises. We want to access our published backend when we are in production, but the team needs to continue accessing the API locally to develop new features in a […]
