If you get this error while running the ng-script in Powershell:  Error: ng : ….\npm\ng.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.LinkID=135170…….. Few Steps to follow: Step 1:  Open your terminal and type the below syntax: set-ExecutionPolicy RemoteSigned -Scope CurrentUser This command set the policies for the current user. Step 2:  Now the second command is: Get-ExecutionPolicy After running this command, it will show “RemoteSigned”. If the RemoteSigned message is received then the problem is resolved. Step 3:  To view the Policy, we need to run the below command: Get-ExecutionPolicy -list The policies are: We can see CurrentUser policy changes to RemoteSigned. We have successfully solved the problem. Now try to run the “ ng version ” angular command in the terminal. Inside the Powershell terminal, the ng command is working. Conclusion By following the a

Introduction: In data processing and analysis, it's often necessary to convert JSON data to CSV format for easier manipulation and compatibility with various tools. While there are multiple libraries available for this task, handling nested JSON objects with varying fields can present a challenge. In this blog post, we'll explore how to convert nested JSON to CSV using Node.js, while dynamically handling fields that may vary between different JSON files. Table of Contents: 1. Understanding the JSON Structure 2. Setting Up the Environment 3. Reading and Parsing the JSON File 4. Dynamic Field Determination 5. Converting JSON to CSV 6. Writing the CSV Output 7. Error Handling and Edge Cases 8. Conclusion and Next Steps Section 1: Understanding the JSON Structure In this section, I have provide an overview of the JSON structure we'll be working with. I will explain the hierarchy of objects and arrays, emphasizing nested objects and fields that may differ across files. Example:

In your HTML file: You have an input field of type "date" with the formControlName "dateOfBirth" . Below that, you have an <div> element with a *ngIf directive to display an error message if the "dateOfBirth" form control has the "invalidDateOfBirth" error. In your TypeScript file: You import the necessary dependencies: FormControl, FormGroup, and FormBuilder from '@angular/forms' . Then, you define a FormGroup named "form" in your component. In the constructor, you inject the FormBuilder and use it to create the form group. The "dateOfBirth" form control is initialized with an empty string as its initial value and a custom validator function named "validateDateOfBirth" . The "validateDateOfBirth" function takes a FormControl as a parameter. It retrieves the value of the control, which is the date of birth entered by the user. It then calls the "calculateAge" function to
