function findSmallestNumber(numbers){
return Math.min.apply(Math, numbers);
}
This code sets the context to be the Math object. However, this is not required because the min() and max() methods will still function properly regardless of the specified context.
How does it successfully execute even when passed as undefined?
Why is there no need to explicitly pass the Math object?
When the apply function is executed, the first argument that is passed will be assigned as the value for this. If the function being called does not make any reference to this, then the specific value of this becomes irrelevant. This is particularly true in the case of Math.min, which does not interact with this during execution.
It should be noted that the information provided is mostly accurate. According to documentation, there is a caveat about the actual value of this when using the method:
It's important to mention that the real value of
thismay differ from what is seen by the function: if the method is part of non-strict mode code, null and undefined values will default to the global object, while primitive values are boxed accordingly.
