This method makes the array immutable. Since array is an object, no element can be added or Conclusion We can prevent mutation of objects and arrays using the Object. freeze() method will fail silently in non-strict mode. freeze ()`, test its behavior against common array operations, explore its limitations, and discuss practical use cases The Object. freeze() method prevents any changes to an object. How to DeepFreeze a nested Object/Array So I believe you’ve read my previous article — ‘Differences between Object. freeze in Javascript Object and Array Const creates a readonly reference to a value, i. Frozen We'll write a deepFreeze () function that will recursively freeze an object and all nested objects or arrays within it. Among the Object constructor methods, the Object.
