Welcome to the block-local-function-declarations- wiki!
In Javascript, it should be possible to redefine a function whithin an another function. It is important to know that the new defined function should only be usable within the scope of that function which contains the new definition. For a better understanding an example shall follow:
function outerFunction()
{
return "Outer function";
}
function anotherFunction()
{
//Redefining
function outerFunction()
{
return "Redefined function";
}
console.log(outerFunction());
}
anotherFunction(); //Outputs "Redefined function"
console.log(outerFunction()); //Outputs "Outer function"
In addition, redefining a function within a block(e.g. within a if statement) should not work like expected in other languages, because Javascript does not support block scoping (NOT COMPLETELY TRUE).
A solution to the example above could be as follows:
