What is the opposite of Object.freeze or Object.seal? Is there a function that has a name such as detach?...
Since the ECMA-262 specifications Javascript has gained the Object.freeze() method, which allows for objects, whose properties can not be changed, added or removed.  var obj = {'a':1, 'b:2'}; Object.freeze(obj); Object.isFrozen(obj);...
I have a simple javascript loop as you seen below:  function runCode() {     $("#sample-span").removeAttr("style");     for (var i = 0; i < 100000; i++) {         console.log(new Date());     }     $("#sample-span").toggleC...

I need to freeze an object/array so it cannot be mutated in any way. Object.freeze() is almost perfect:  const arr = []; const obj = { foo: "bar" }; let frozenArr = Object.freeze(arr); let frozenObj = Object.freeze(obj);  // Uncaught TypeErro...
I execute user-provided javascript code inside iframes. It is possible that the executed code was submitted by a different user, so it needs to be sandboxed as much as possible. The sandbox attribute on the iframe helps a great deal, as does using a...
