What is the output of the following code? “`js function counter() { let count = 0; return () => ++count; } const inc = counter(); console.log(inc()); console.log(inc()); “`

Accepted Answer

The output of the code is 1, 2 because each time the function inc is called, it increments the count variable by 1. The initial count is 0, so the first call to inc returns 1, and the second call returns 2.
