Examples

The following snippet creates a new CompileError instance, and logs its details to the console:

try {
  throw new WebAssembly.CompileError('Hello', 'someFile', 10);
} catch (e) {
  console.log(e instanceof CompileError); // true
  console.log(e.message);                 // "Hello"
  console.log(e.name);                    // "CompileError"
  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
}
