MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The for loop is an iterative statement which you use to check for certain conditions and then repeatedly execute a block of code as long as those conditions are met.

Detailed explanation-2: -A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.

Detailed explanation-3: -In JavaScript an iterator is an object which defines a sequence and potentially a return value upon its termination. Specifically, an iterator is any object which implements the Iterator protocol by having a next() method that returns an object with two properties: value. The next value in the iteration sequence.

Detailed explanation-4: -JavaScript Iterators The iterator protocol defines how to produce a sequence of values from an object. An object becomes an iterator when it implements a next() method. The next() method must return an object with two properties: value (the next value)

Detailed explanation-5: -A for loop repeats until a specified condition evaluates to false. The JavaScript for loop is similar to the Java and C for loop. When a for loop executes, the following occurs: The initializing expression initialization, if any, is executed.
