Javascript loops MCQ

The three critical manipulations of a loop variable in a for loop are initialization, testing, and updating.
The loop first initialises the variable, then tests the condition, and finally increments its value after executing the statement.

The interpreter converts the source code into machine code, line by line, and halts when it encounters an error.
Before processing each line, the interpreter evaluates the variable expression and assigns the property name (a string value) to it.

If the body of a for/in loop removes a property that has not yet been enumerated, that property will not be included in the loop.
Additionally, if the body of the loop adds new properties to the object, those properties will typically not be enumerated.

The continue keyword causes the loop to move on to the next iteration from the point at which it is encountered, whereas the break keyword exits the loop entirely.

The debugger statement typically has no effect. However, if a debugger is available and running, the implementation may (but is not required to) perform some kind of debugging action.
In practice, this statement functions like a breakpoint, causing the execution of JavaScript code to stop and allowing you to use the debugger to print out the values of variables.

If a property on an object is deleted during a for/in loop before it is enumerated, it will not be enumerated.
Additionally, properties that are defined within the body of the loop will typically not be included in the enumeration.

When an exception is raised in a jump statement, the interpreter will navigate to the closest exception handler, this handler could be located either in the same function or in an outer function that invoked it.

The continue statement is used to skip the current iteration and move to the next one, unlike the break statement which terminates the loop.

The debugger statement typically doesn't have any effect when executed.
However, if a debugging program is active and running, it may trigger some type of debugging action.
Essentially, this statement acts like a breakpoint, which means the execution of JavaScript code will be halted, and you will be able to examine variable values using the debugging tools.

The "use strict" directive is a way to opt-in to a restricted variant of JavaScript.
The purpose of "use strict" is to indicate that the code should be executed in "strict mode".
This is a way to opt-in to a restricted variant of JavaScript, which can help you write "safer" JavaScript.
