Examples
Creating a new LinkError instance
The following snippet creates a new LinkError
instance, and logs its details to the console:
try { throw new WebAssembly.LinkError('Hello', 'someFile', 10); } catch (e) { console.log(e instanceof LinkError); // true console.log(e.message); // "Hello" console.log(e.name); // "LinkError" console.log(e.fileName); // "someFile" console.log(e.lineNumber); // 10 console.log(e.columnNumber); // 0 console.log(e.stack); // returns the location where the code was run }
