What is the output of the following? “`js const obj = {}; Object.defineProperty(obj, ‘x’, { get() { return 42; }, set(v) { console.log(‘set:’, v); } }); obj.x = 10; console.log(obj.x); “`

What is the output of the following? “`js const obj = {}; Object.defineProperty(obj, ‘x’, { get() { return 42; }, set(v) { console.log(‘set:’, v); } }); obj.x = 10; console.log(obj.x); “`

Accepted Answer

The output is "set: 10 then 42" because when the property `x` is set to 10, the setter function logs "set: 10" to the console. Then, when `obj.x` is accessed, the getter function returns 42.
