Salesforce custom labels can be used across different Salesforce technologies, including Apex, Visualforce, Aura components, and Lightning Web Components (LWC). Here's how you can use custom labels in each of these contexts: Apex : In Apex, you can access custom labels using the System.Label global variable. Custom labels are referenced by their developer name. String labelValue = System.Label.MyCustomLabel; Visualforce : In Visualforce pages, you can reference custom labels using the $Label global variable. <apex:outputText value="{!$Label.MyCustomLabel}" /> Aura Components: In Aura components, you can access custom labels using the $Label global value provider. <aura:component>     <aura:attribute name="labelValue" type="String" default="{!$Label.MyCustomLabel}" /> </aura:component> Lightning Web Components (LWC): In Lightning Web Components, you can import and reference custom labels using the @salesforce/label scop...

Here's an example to display a list of contacts related to an account and add new contacts and update existing ones. <!-- ContactList.cmp --> <aura:component controller="ContactController">     <aura:attribute name="accountId" type="String" />     <aura:attribute name="contacts" type="List" />     <aura:handler name="init" value="{!this}" action="{!c.init}" />     <ul>         <aura:iteration items="{!v.contacts}" var="contact">             <li>{!contact.Name}</li>         </aura:iteration>     </ul> </aura:component> ========================================================================== // ContactController.cls public with sharing class ContactController {     @AuraEnabled     public static List<Contact> getContacts(String accountId) {         retu...

Aura Components  Aura components are the self-contained and reusable units of an app. They represent a reusable section of the UI, and can range in granularity from a single line of text to an entire app. The framework includes a set of prebuilt components. For example, components that come with the Lightning Design System styling are available in the lightning namespace. These components are also known as the base Lightning components. You can assemble and configure components to form new components in an app. Components are rendered to produce HTML DOM elements within the browser. A component can contain other components, as well as HTML, CSS, JavaScript, or any other Web-enabled code. This enables you to build apps with sophisticated UIs. The details of a component's implementation are encapsulated. This allows the consumer of a component to focus on building their app, while the component author can innovate and make changes without breaking consumers. You configure components ...

Dynamically invoking JavaScript functions enhances code flexibility and efficiency. By dynamically calling JavaScript functions, we can create more flexible and efficient applications that adapt to various scenarios. Dynamic Functionality : Dynamically calling JavaScript functions allows your code to adapt to different scenarios and conditions at runtime. This flexibility lets you execute functions based on user interactions, system events, or data-driven logic. Code Reusability : By dynamically invoking JavaScript functions, you can reuse standard functions across multiple components or modules within your application. This promotes code modularity, reduces duplication, and leads to cleaner and more maintainable code. Conditional Logic: Dynamically invoking functions allows you to apply conditional logic to determine which functions to execute based on specific conditions or criteria. This enables you to build more intelligent and adaptive applications that respond dynamically to cha...
