Q5. Debug the following code: var a=10; function abc() { console.log(a); var a=2; } abc();
Ans. 
The code will output 'undefined' because variable 'a' is hoisted within the function.
• Variable 'a' is hoisted to the top of the function scope, so when 'console.log(a)' is called, 'a' is undefined.

• To fix this, move the declaration of 'var a=2;' above the 'console.log(a);' statement.
