Question
What will the value of Var be in the following code snippet?
var Var='var';
var Var;
Solution
In JavaScript, when you declare a variable with var, it gets hoisted to the top of its scope, but its assignment happens where it appears in the code.
- Variable Declaration: The line
var Var='var';declares a variableVarand immediately assigns it the string'var'. - Second Declaration: The line
var Var;is a second declaration of the same variableVar. Due to hoisting, this does not change the value that was assigned earlier.
After executing both lines, the variable Var will still hold the value assigned to it in the first line.
Final Answer
The value of Var will be 'var'.
