— Check if it exists in your code I mean
Is there a more simple solution to this? Use case involves 2 functions, both accept any args (using rest operator) but one has to call the other func...
function someFunc(...args) {
// do something
}
function myFunc(...args) {
someFunc.apply(thisarg, args);
}
— I get I can use rest operator again instead of apply too, but apply actually is needed here
— Example real code:
FORK_CHILD: function (bg = false, ...args) {
const pid = this.sysCallProcedures.FORK.call(this, bg, ...args);
this.curProc.childPids.add(pid);
return pid;
},
— That was one of my first thoughts but they're part of the prototype
— Kernel.prototype.sysCallProcedures

— I want the this var for Kernel.prototype.sysCallProcedures.ANYTHING to be set to the instance of Kernel
— But because they're in the sysCallProcedures object, this is undefined unless I use apply or call
—
var test = function () {
this.thing = "Hello world";
};
test.prototype.stuff = {
testFunc: function () {
console.log(this.thing);
}
};
var testInstance = new test();
testInstance.stuff.testFunc();
VM505:6 undefined
