Other code cannot delete or change its properties. {{jsxref(\"Object.fromEntries()\")}} : Returns a new object from an iterable of [key, value] pairs. (This is the reverse of {{jsxref(\"Object.entries\")}}). {{jsxref(\"Object.getOwnPropertyDescriptor()\")}} : Returns a property descriptor for a named property on an object. {{jsxref(\"Object.getOwnPropertyDescriptors()\")}} : Returns an object containing all own property descriptors for an object. {{jsxref(\"Object.getOwnPropertyNames()\")}} : Returns an array containing the names of all of the given object's own enumerable and non-enumerable properties. {{jsxref(\"Object.getOwnPropertySymbols()\")}} : Returns an array of all symbol properties found directly upon a given object. {{jsxref(\"Object.getPrototypeOf()\")}} : Returns the prototype (internal [[Prototype]] property) of the specified object. {{jsxref(\"Object.groupBy()\")}} : Groups the elements of a given iterable according to the string values returned by a provided callback function. The returned object has separate properties for each group, containing arrays with the elements in the group. {{jsxref(\"Object.hasOwn()\")}} : Returns true if the specified object has the indicated property as its _own_ property, or false if the property is inherited or does not exist. {{jsxref(\"Object.is()\")}} : Compares if two values are the same value. Equates all NaN values (which differs from both IsLooselyEqual used by == and IsStrictlyEqual used by ===). {{jsxref(\"Object.isExtensible()\")}} : Determines if extending of an object is allowed. {{jsxref(\"Object.isFrozen()\")}} : Determines if an object was frozen. {{jsxref(\"Object.isSealed()\")}} : Determines if an object is sealed. …\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
