for Loop Execution Order

Step by step

Understanding the execution order prevents bugs:

for (let i = 0; i < 3; i++) {
  console.log(i)
}

Execution:

$1.$ let i = 0 (once)

$2.$ Check i < 3 → true

$3.$ Run body: log $0$

$4.$ i++ → i is $1$

$5.$ Check i < 3 → true

$6.$ Run body: log $1$

...continues until i < 3 is false
