function

jsc.jscDescribe

function jscDescribe(
value: any
): string;

Returns JavaScriptCore's debug description of a value: how the value is represented (Int32, Double, String, Object, and so on) and, for values on the heap, its address and its Structure (hidden class).

Renamed from "describe" to avoid confusion with the test runner.

import { jscDescribe } from "bun:jsc";

jscDescribe(1); // "Int32: 1"
jscDescribe({ a: 1 }); // "Object: 0x... with butterfly (nil) (Structure 0x...:[..., Object, (1/2, 0/0){a:0}, NonArray, ...]), StructureID: ..."
