Methods\nlike [SlidesApp.openById()](/apps-script/reference/slides/slides-app#openbyidid)\nand [SlidesApp.getActivePresentation()](/apps-script/reference/slides/slides-app#getactivepresentation)\nload an existing Slides presentation, while\n[SlidesApp.create()](/apps-script/reference/slides/slides-app#createname)\ncreates a new presentation. These methods return a\n[Presentation](/apps-script/reference/slides/presentation) object that\nrepresents the loaded presentation.\n\nOnce a presentation is open, it does not receive any further updates from\ncollaborators. Presentations are usually opened at their latest version that has\nbeen saved in Drive. However, if a script is container-bound to a presentation,\nthat presentation will be loaded at the same version as the accompanying Slides\neditor.\n\nModifying a presentation\n------------------------\n\nOnce a presentation is open, a script can read and modify it. Any changes that\nthe script makes to the presentation are reflected in subsequent reads and\nmodifications for the duration of the script execution.\n\nSaving changes\n--------------\n\nAfter making changes to a presentation, the changes are saved all at once\nwhen the script execution completes, or when [Presentation.saveAndClose()](/apps-script/reference/slides/presentation#saveandclose) is\ncalled. After changes are saved, they propagate asynchronously to the\nuser's editor, as if the changes were made by a collaborator.\n\nAfter a presentation is closed using `Presentation.saveAndClose()`, it can be\nreopened for editing using one of the presentation loading methods."]]
