Why is it okay to add properties to an object after assigning a method directly to the object? The quote hasn"t changed? Very strange-sharp-sharp-sharp topic description
/ / Please paste the code text below (do not replace the code with pictures)
Function is a reference object. Why can't attributes be added
var c = function(a, b){};
c.g = 4;
console.log(c.length)//2
console.log(c.g)//4reference has changed. It's just that the function is also an object , so it's OK to add a c attribute to the object; similarly, you can also add a c attribute to an array
do not know that everything in js is an object, you don't have to declare a function directly and add an attribute in the first step, and the result is the same
