// Question 1:
// What will the following lines output?
/* console.log(false == '0')
console.log(false === '0')
console.log(0.1 + 0.2);
console.log(0.1 + 0.2 == 0.3); */
// Question 2:
// What will be output to the console and why?
/* var myObject = {
foo: "bar",
func: function() {
var self = this;
console.log("outer func: this.foo = " + this.foo);
console.log("outer func: self.foo = " + self.foo);
(function() {
console.log("inner func: this.foo = " + this.foo);
console.log("inner func: self.foo = " + self.foo);
}());
}
};
myObject.func(); */
// Question 3:
// Although typeof bar === "object" is a reliable way of checking if bar is an object,
// the surprising gotcha in JavaScript is that null is also considered an object!
// Fix the following so it logs false...
/* var bar = null;
console.log(typeof bar === "object"); // logs true!
console.log((bar !== null) && ((typeof bar === "object") || (typeof bar === "function"))); */
// Question 4
/* for (let i = 0; i < 5; i++) {
setTimeout(function() { console.log(i); }, i * 1000 );
} */
