Is it possible to evaluate several conditions in the second part of a JavaScript for loop statement?

Is it possible to execute the following:

for (let i = r-1; i < r+2, i < numRows, i >= 0; i++)

Answer №1

A helpful tip: When writing a for loop in JavaScript, keep in mind that the comma operator only returns the result of the last expression. So if you want to include multiple conditions before executing the loop, consider using logical AND instead.

for (var row = r-1; row < r+2 && row && numRows && row >= 0; row++)

Just a reminder, you can use any expression in each section of a for statement, except for directly using the 'in' operator in the first section. Keep experimenting with different expressions to see what works best for your code!
