Knowledge Point: The Array.prototype.every () method tests whether all elements of an array pass the test of the specified function. Code:

1 functionevery (collection, pre) {2   //Is everyone being true?3   functionisFit (element, index, array) {4     returnElement[pre];5   }6   varrf=collection.every (isFit);7  8   returnRF;9 }Ten  OneEvery ([{"User": "Tinky-winky", "Sex": "Male"}, {"User": "Dipsy", "Sex": "Male"}, {"User": "Laa-laa", "Sex": "Female"}, {"U Ser ":" Po "," Sex ":" Female "}]," sex ");
