What will be the output of the following JavaScript code: console.log(2 + '2');?

When evaluating the expression 2 + '2', JavaScript performs type coercion due to the presence of both a number and a string in the operation. In this scenario, the number 2 is combined with the string '2'.

JavaScript will attempt to convert the number into a string to accommodate the operation, as the + operator performs string concatenation when one of the operands is a string. Therefore, the number 2 gets converted to the string '2'.

After this conversion, the operation becomes '2' + '2', which results in the concatenated string '22'.

Thus, when the code console.log(2 + '2'); is executed, it prints '22' to the console. This explains why the output is the string '22' and confirms that the answer is indeed the first choice.
