In JavaScript, if the + operator is used in an arithmetic expression, what is the result?

Explanation:
In JavaScript, the + operator performs numeric addition when the operands are numbers. In arithmetic expressions, it calculates the sum of the values. JavaScript does perform type coercion, so if one operand is a string, the operation becomes string concatenation instead of numeric addition, and no error is thrown. For example, 5 + 10 equals 15, but 5 + '10' results in '510'. The behavior in arithmetic contexts is to add numbers, which is why summing the values is the correct outcome in this scenario.
