Example

The following example shows both uses of the clearMeasures() method.

function clear_measure(name) {
  if (performance.clearMeasures === undefined) {
    console.log("performance.clearMeasures Not supported");
    return;
  }
  // Remove all "measure" performance entry types with the specified name
  performance.clearMeasures(name);
}
function clear_all_measures() {
  if (performance.clearMeasures === undefined) {
    console.log("performance.clearMeasures Not supported");
    return;
  }
  // Remove all "measure" type performance entries from the performance buffer
