Here is the code snippet I am working with:
im.size((function(a, b) {
console.log(b);
console.log(im);
})(im));
The Object "im" has a function called size, which requires a callback function. It passes the parameters a and b to this callback function. However, I need to ensure that the object "im" is accessible within the callback. In my current approach, I pass it as an argument from the outside, but this seems to override the values of a and b passed to the callback.
When this code runs, the output is:
undefined [My Object]
If I modify the code to be like this:
im.size(function(a, b) {
console.log(b);
console.log(im);
});
The output changes to:
17 [My object] // edited: was undefined before
How can I ensure that the object "im" is available in the scope of the callback without losing the original variables passed to it? Any insights or explanations on this issue would be greatly appreciated.
Edit: Upon further exploration, I realized that the outer scope is actually accessible in my initial example. Does this accessibility also apply to asynchronous callbacks and what is the reason behind the outer scope being accessible in this manner?
