Question One

A variable is referred to as a data name within the storage where the programs operate. It consists

of letters, digits, and underscore characters. In other words, variables are regarded as data values

that can change during the execution of a program. When the user is asked a question, the data

values can easily change during the performance.

Variable scope is a programming block under which a variable is assigned or simply the life of a

variable. For example; function foo() { var x; }.

Local variable and Global variable are the two shared variables known.

A local variable is regarded as a variable that only exists and is assigned within the programming

block and can only be declared within the block. They get destroyed automatically when the

function's execution is terminated, while they exist only when the process is under

implementation.

A global variable is a type of variable defined externally within a function.

A variable can be declared inside a function for local variables, outside the process for global

variables, and within the definition of function parameters for the formal parameters.

Global variables can be accessed from all program modules. It is capable of keeping consistency

since it stores constants. When various functions can be accessed through the same data, the

global variable becomes effective.

Variable values remain intact when running a task when you use a local variable. Memory space

is created when a program terminates when using local variables. You can change names easily

in a local variable since the local variable is only meaningful where declared.
