Given the following code: var myVar = '5'; var myAddedVar = myVar + 10; What is the value of (myAddedVar.constructor === Number)?

Difference between the two declaration methods below? var functionOne = function() { /* some code */ } function functionTwo() { /* some code */ }

What is the output? var one; var two = null; console.log(one == two, one === two);

Which is NOT a valid way to write a loop that will iterate over the values in the array in variable 'myArray'?

An (inner) function enjoys access to the parameters and variables of all the functions it is nested in. This is called:

(function() { 'use strict'; foo = 'bar'; })();

How can you set DOM element style assuming there is an element with id='id'?

How can you remove spaces, tabs and line terminator characters around the string? String is defined like this: let string = 'hey'

Select the statement that will return truthy value. Array let a = [1,2,3,4] is defined

Which statement returns false. First line in file is: var a = true; b = false; This code will throw an error delete a === b
