What will be the output of the following JavaScript code snippet?int a...
Explanation:
The given code snippet is written in JavaScript language. It checks the value of variable 'a' and returns 1 if it is not null, otherwise it returns 0.
Conditional Statements:
The code snippet contains a conditional statement that checks the value of variable 'a' using the not equal to operator (!=). The not equal to operator returns true if the compared values are not equal, otherwise it returns false. In this case, the code checks if variable 'a' is not equal to null.
int a=1;
The code initializes a variable 'a' with a value of 1.
if(a!=null)
The code checks if the value of variable 'a' is not equal to null.
return 1;
If the value of variable 'a' is not null, the code returns 1.
else
If the value of variable 'a' is null, the code executes the else block.
return 0;
The else block returns 0.
Output:
Since the value of variable 'a' is not null, the code returns 1.
Therefore, the correct answer is option 'B'.
