Use for Cycle through odd numbers / even numbers

for ( let i=1; i<=10; i++){
    
	if(i % 2) continue; // When i%2 When it is an odd number, continue to execute , Print when even 
	console.log;
}

Here is when the third odd number appears , Just stop Exit loop

let count = 0;  // Define a counter , The default is 0
for ( let i=1; i<=10; i++){
    
	if (i%2){
    
		if ( count++ = 3) break;   // When the counter is equal to 3  When it's time to exit the loop 
	}
	console.log(i);
}
