Continue statement in Javascript - Step-by-Step Execution

Concept Flow - Continue statement

Start loop iteration

↓

Check condition

Yes↓

Check continue condition

↓

Skip rest

↓

Next iteration

No↓

Exit loop

Each loop iteration checks if it should skip the rest using continue; if yes, it jumps to the next iteration immediately.

Execution Sample

Javascript

for(let i=0; i<5; i++) {
  if(i === 2) continue;
  console.log(i);
}

This code loops from 0 to 4, but skips printing when i is 2.

Execution Table

Iteration	i	Condition i<5	Check if i===2	Action	Output
1	0	true	false	Print 0	0
2	1	true	false	Print 1	1
3	2	true	true	Continue (skip print)
4	3	true	false	Print 3	3
5	4	true	false	Print 4	4
6	5	false	-	Exit loop

💡 i reaches 5, condition i<5 is false, loop ends

Variable Tracker

Variable	Start	After 1	After 2	After 3	After 4	After 5	Final
i	0	1	2	3	4	5	5

Key Moments - 2 Insights

Why does the loop skip printing when i is 2?

Because at iteration 3 (i=2), the condition i===2 is true, so continue runs and skips the print step as shown in the execution_table row 3.

Does continue stop the whole loop?

No, continue only skips the rest of the current iteration and moves to the next one, as seen in the flow and execution_table rows.

Visual Quiz - 3 Questions

Look at the execution_table, what is the output at iteration 3?

A 2

B No output

C 3

D Error

💡 Hint

Check the 'Output' column at iteration 3 in the execution_table.

At which iteration does the loop stop running?

A Iteration 4

B Iteration 5

C Iteration 6

D Iteration 3

💡 Hint

Look at the 'Condition i<5' column and the exit_note in the execution_table.

If we remove the continue statement, what will happen at iteration 3?

A It will print 2

B It will skip printing

C It will cause an error

D It will exit the loop

💡 Hint

Without continue, the print action happens every iteration as shown in the execution_table except when continue is used.

Concept Snapshot

continue statement in loops:
- Skips the rest of current iteration
- Moves immediately to next iteration
- Useful to skip specific cases
Syntax:
for(...) { if(condition) continue; ... }

Full Transcript

This visual trace shows how the continue statement works in a JavaScript for loop. The loop runs from i=0 to i=4. When i equals 2, the continue statement runs, skipping the print step for that iteration. The loop then continues with i=3. The variable i increments each iteration until it reaches 5, where the loop ends because the condition i<5 becomes false. The key point is that continue does not stop the loop, it only skips the rest of the current loop cycle and moves to the next one.
