Question
Consider this code snippet: 'const [a, b] = [1,2,3,4] '. What is the value of b?1 pointundefined12[1,2,3,4]
Solution
The value of 'b' is 2. This is because the code snippet is using destructuring assignment in JavaScript to assign the values of the array [1,2,3,4] to the variables 'a' and 'b'. 'a' is assigned the first value of the array (1), and 'b' is assigned the second value of the array (2). The remaining values in the array are ignored because there are no more variables to assign them to.
