TypeScript is a programming language that adds typing and interfaces to JavaScript. Here you will find Standards, Best Practices, and Examples for TypeScript

TypeScript

Like JavaScript in TypeScript we use camelCase most times for variables. However for "interface", "type" and "enum" we use PascalCase


type Result = "success" | "failure"

enum PermissionCodes {
  SITE_ADMIN = 'SiteAdmin',
  ORG_LEADER = 'OrgLeader',
  ORG_ADMIN = 'OrgAdmin',
  ORG_MEMEBER = 'OrgMember',
  PROJECT_LEADER = 'ProjectLeader',
  PROJECT_ADMIN = 'ProjectAdmin',
  PROJECT_MEMBER = 'ProjectMember',
  MEMBER = 'Member',
}

interface Item {
  id: string;
  title: string;
  sections?: Section[];
}
