Last Updated: 18 May 2024

Deep freezes an object.

  • Use Object.keys() to get all the properties of the passed object, Array.prototype.forEach() to iterate over them.
  • Call Object.freeze(obj) recursively on all properties, applying deepFreeze() as necessary.
  • Finally, use Object.freeze() to freeze the given object.
const deepFreeze = obj => { Object.keys(obj).forEach(prop => { if (typeof obj[prop] === 'object') deepFreeze(obj[prop]); }); return Object.freeze(obj); };
'use strict'; const val = deepFreeze([1, [2, 3]]); val[0] = 3; // not allowed val[1][0] = 4; // not allowed as well
