Functions ​

FunctionDescription

clearReusedRange

Clears the reused Range object.

This should be called when you need to ensure the cached Range is properly released, particularly when switching contexts or cleaning up resources.

Example

typescript
const range = textRange(textNode, 0, 5);
// ... use range ...
clearReusedRange(); // Clean up when done

textRange

Creates or reuses a DOM Range for a text node.

Note: This function always returns the same Range object for performance reasons. DOM Range objects are expensive to create and can slow down subsequent DOM updates. Call clearReusedRange() if you need to ensure the range is properly released.

Example

typescript
const textNode = document.createTextNode("Hello World");
const range = textRange(textNode, 0, 5); // Selects "Hello"
