What type of value gets printed if we add the following two variables ?
var a = "10";var b = 50;
A)
B)
C)
D)
Explanation:
In JavaScript, the +
operator can act as both an arithmetic operator and a string concatenation operator, depending on the type of operands.
Here:
a
is a string ("10"
).b
is a number (50
).
When a string is involved in an addition operation, JavaScript concatenates the string with the number, converting the number to a string.
So, the result of adding "10" + 50
will be the string "1050"
(string concatenation).
Thus, the correct answer is:
(B) Text.
