Question
What will be the output of the following JavaScript code? var a=5 , b=11 var obj = { a : 10 } // with keyword in JavaScript with(obj) { alert(b) }Select one:a. 15b. 5c. Errord. 11
Solution
The output of the given JavaScript code will be:
d. 11
Explanation:
- We declare two variables,
awith a value of 5 andbwith a value of 11. - We also declare an object
objwith a propertyaand a value of 10. - The
withkeyword in JavaScript allows us to access the properties of an object without explicitly referencing the object name. - Inside the
with(obj)block, we use thealert()function to display the value ofb. - Since
bis not a property of theobjobject, JavaScript will look forbin the outer scope, which is the global scope. - In the global scope,
bhas a value of 11, so thealert()function will display 11 as the output.
