I attempted to implement a custom isEmpty function for the Object prototype as follows:
Object.prototype.isEmpty = function() {
for (var key in this) {
if (this.hasOwnProperty(key)) {
return false
}
}
return true
}
However, when trying to use this function, I encountered the following error:
Uncaught TypeError: slots[name$1].every is not a function
My project involves using Vue.js version 2.6.
Could you explain why this error occurred and suggest the best approach to adding custom methods like isEmpty to the Object prototype? I have tested similar functions with success on Array and String objects, but facing issues specifically with Object.
