How do I declare a constant object in JavaScript? For example:
/* meu código */
object_teste = {valor:5}
/* console navegador */
object_teste.valor=10;
console.log(object_teste.valor) // aqui ele me retorna 10 ao invés de 5
How to leave this value constant? As if it were a constant variable but in this case an object.
I think something like Object.freeze(object_teste); solves your problem.
This function "freezes" the object, leaving it immutable.
I think the script below will help with recursion in case you need to freeze sub objects:
Object.prototype.recursiveFreeze = function() {
for(var index in Object.freeze(this)) {
if(typeof this[index] == 'object') {
this.recursiveFreeze.call(Object.freeze(this[index]));
}
}
}
// Uso:
myObject.recursiveFreeze();
