6. Consider the following JavaScript skeletal program: // The main program var X; function sub1() { var x; function sub2 () { function sub3 () { Assume that the execution of this program is in the following unit order: main calls subl subl calls sub2 sub2 calls sub3 a. Assuming static scoping, in the following, which declaration of x is the correct one for a reference to x? i. subl ii. sub2 iii. sub3 b. Repeat part a, but assume dynamic scoping.

A computing algorithm is a set of instructions or a process for solving computational problems. In other words, it contains a set of rules that indicate the step-wise process to solve a problem. The algorithm takes a set of inputs, executes the instructi…
