• src/assets/wise5/services/nodeService.ts:

  • Removed the 'use strict'; directive.
  • Renamed ConfigService, ProjectService, and DataService to configService, projectService, and dataService respectively throughout the file. [1] [2] [3] [4] [5] [6] [7] [8]

• src/assets/wise5/services/studentNodeService.ts: Renamed DataService and ProjectService to dataService and projectService respectively in getNextNodeId, resolveNextNodeIdFromTransition, and getNextNodeIdFromParent methods. [1] [2] [3]

• src/assets/wise5/services/teacherNodeService.ts: Renamed DataService and ProjectService to dataService and projectService respectively in getNextNodeId method. Also, formatted the observable declaration for better readability. [1] [2]
