KeyboardLayoutMap: entries() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The entries() method of the KeyboardLayoutMap interface returns a new Iterator object that contains the key/value pairs, in the same order as that provided by a loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

The method is otherwise the same as Map.prototype.entries().


A new Iterator object.


The following example iterates every location- or layout-specific string and its associated keyboard code on an English QWERTY keyboard.

navigator.keyboard.getLayoutMap().then((keyboardLayoutMap) => {
  for (const [code, key] of keyboardLayoutMap.entries()) {
    console.log(`${code} keyboard code represents ${key} key`);
