{
  "lint": {
    "rules": {
      "include": ["for-direction"],

Requires for loop control variables to increment in the correct direction.

Incrementing for loop control variables in the wrong direction leads to infinite loops. This can occur through incorrect initialization, bad continuation step logic or wrong direction incrementing of the loop control variable.

Invalid:

// Infinite loop
for (let i = 0; i < 2; i--) {}

Valid:

for (let i = 0; i < 2; i++) {}
