Google Apps Script has acquired a significant upgrade ever because it was first launched to the general public greater than a decade in the past. Apps Script now makes use of the V8 JavaScript Engine – it’s the identical runtime that’s used contained in the Google Chrome browser and the favored Node.js surroundings.
This primarily means:
- Builders can write code utilizing trendy JavaScript syntax like Arrow Capabilities, Courses, Array Destructuring, Template Literals and extra.
- The V8 Engine is quick, highly effective and constantly enhancing, It can doubtless enhance the efficiency and reminiscence utilization of your Google Scripts.
- Builders can use new JavaScript ES6 options like Symbols, Iterators, Turbines, Guarantees, Maps, Units and Proxies that weren’t out there within the earlier model of Google Apps Script.
Chrome V8 JavaScript Engine
Any new initiatives that you just create contained in the Google Apps Script editor mechanically use the brand new V8 runtime.
If you want to improve any previous undertaking to make use of V8, go to the Run menu and select “Allow new Apps Script runtime powered by V8.” If you don’t see this selection but, add a brand new runtimeVersion discipline in your undertaking’s manifest file with the worth of V8. You may set the worth to DEPRECATED_ES5 to change to the previous model that makes use of the Mozilla’s Rhino JavaScript engine.

ES6 Modules – The Lacking Half
ES6 launched the idea of modules in JavaScript which permits builders to jot down reusable code that can be simpler to refactor and preserve. You may break your program into separate recordsdata (modules) after which import them into different modules utilizing import-export statements.
The brand new Google Apps Script surroundings doesn’t assist ES6 modules.
The opposite massive change is that features turn into out there primarily based on the sequence of recordsdata within the script editor. Let me clarify.
Say your Apps Script undertaking has a whole lot of recordsdata and you’ve got created two features of the identical title however they’re situated in several recordsdata. Apps Script gained’t complain however when you possibly can name this operate, the one that’s outlined within the bottom-most file of the undertaking can be invoked.
If you happen to favor the benefit of working with ES6 Modules, the Apps Script Starter kit may help. You may write code regionally inside Visible Studio Code, bundle the modules right into a single file with Webpack after which push the bundle to the cloud mechanically with Clasp.
The starter package has additionally been up to date to make use of the brand new V8 Runtime. Watch this YouTube video to learn to develop with Google Scripts utilizing the Starter Package.
Efficiency – V8 vs Vanilla JavaScript
Eric Koleda writes – “The efficiency story is blended. Vanilla JavaScript code (looping, math) runs quicker, however calls to Google Workspace providers (SpreadsheetApp, and so forth) run barely slower. Whereas not perfect, we’ve all the time beneficial that performance-intensive apps are normally a greater match for different platforms. On the whole Apps Script is making an attempt to optimize for ease-of-use, not throughput. If efficiency is crucial to your use case then you could need to examine Google Cloud Capabilities, and so forth.”
