// Topic: `var` Keyword (Not Recommended)

// Note:

// -> It can be initialized later.

// -> It can be reassigned.

// -> It can be redeclare in same scope.

// -> It can be redeclare in different scope.

// Note

// Variable declared with var keyword:

// - If it has global scope, it can be accessed inside anywhere.

// - If it has function scope, it can be accessed only inside the function where it is declared.

// - If it has block scope (like if, for, while), it can still be accessed outside the block, Globally and also inside functions.

// Syntax:

// var variableName = value;

// Example:

// Initialized later

var variable;

variable = "value";

// Reassigned

var variable = "value1";

variable = "value2";

// Redeclare

// - As you can see your are using same variable name twice.

// - It will take latest updated value.

var variable = "value1";

var variable = "value2";
