Salesforce Apex
Salesforce Apex is a strongly-typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Salesforce platform. It is used to add business logic to system events, perform custom validations, create complex workflows, and integrate with external services. Apex runs entirely on the Salesforce Lightning Platform and is tightly integrated with the Salesforce data model and user interface.
Developers should learn Apex when building custom applications, automating business processes, or extending Salesforce CRM functionality beyond what is possible with declarative tools like Flow or Process Builder. It is essential for creating triggers, batch jobs, RESTful web services, and complex data manipulations in Salesforce environments, particularly for enterprise-level implementations requiring custom logic.
