Infinite for loop in javascript

 for (let i = 0; i < 10; i--) {

  // 'i' starts at 0 and keeps decreasing (0, -1, -2, ...), 

  // so the condition 'i < 10' is always true.

}

======================

for (;;) {

  // Code to be executed indefinitely

}

==================

for (let i = 0; true; i++) {

  // This condition is always true

}

====================

for (let i = 0; i !== 10; i += 2) {

  // 'i' takes values 0, 2, 4, 6, 8, 10, 12...

  // The condition 'i !== 10' is true for all these values,

  // including 10 because the exact value of 10 is skipped.

  // Better to use '<=' or '>=' for numeric range conditions.
