What is the result of the following code snippet? console.log(1 + '2');

Explanation

JavaScript performs type coercion when using the '+' operator with a string and a number. The number 1 is converted to the string '1', and the two strings are concatenated, resulting in '12'. This is a fundamental behavior of JavaScript's dynamic typing system.

Key points

The '+' operator triggers string concatenation if one operand is a string.
JavaScript automatically coerces types to perform operations.
Numeric addition only occurs if both operands are numbers.
