What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Converting Range in Google Spreadsheet as Image using Google Apps Script

This is a sample script for converting a range in Google Spreadsheet as an image data using Google Apps Script. Unfortunately, there are no methods for directly converting the range in Google Spreadsheet as an image data in the built-in functions. So in this case, as a workaround, Charts Service is used.

Sample script

const range = "B5:D10";
const [header, ...values] = SpreadsheetApp.getActiveSheet()
 .getRange(range)
