JavaScript provides control statements that help manage how loops and conditions behave. Two important statements used inside loops are break and continue. These statements allow developers to control the flow of execution more efficiently.<\/p>\n\n\n\n
The break statement is used to stop a loop completely when a specific condition is met. Once break is executed, the loop ends immediately and the program continues with the next part of the code.<\/p>\n\n\n\n
for (let i = 1; i <= 10; i++) {
if (i === 5) {
break;
}
console.log(i);
}<\/code><\/pre>\n\n\n\nIn this example, the loop stops when the value of i becomes 5. The output will display numbers from 1 to 4 only.<\/p>\n\n\n\n
Understanding Continue Statement<\/h2>\n\n\n\n
The continue statement is used to skip a specific iteration of a loop. Instead of stopping the loop, it moves to the next iteration.<\/p>\n\n\n\n
Example of Continue<\/h3>\n\n\n\nfor (let i = 1; i <= 5; i++) {
if (i === 3) {
continue;
}
console.log(i);
}<\/code><\/pre>\n\n\n\nIn this example, when i is 3, the loop skips that iteration. The output will display 1, 2, 4, and 5.<\/p>\n\n\n\n
Key Differences Between Break and Continue<\/h2>\n\n\n\n
Break stops the entire loop execution
Continue skips only one iteration and continues the loop
Break exits the loop completely
Continue keeps the loop running<\/p>\n\n\n\n
When to Use Break and Continue<\/h2>\n\n\n\n
Use break when you want to stop a loop early based on a condition
Use continue when you want to skip certain values but continue looping<\/p>\n\n\n\n
Practical Use Cases<\/h2>\n\n\n\n
Stopping a search when a result is found
Skipping invalid or unwanted data during processing
Improving performance by avoiding unnecessary iterations<\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
Break and continue statements are essential for controlling loops in JavaScript. They help make code cleaner, more efficient, and easier to manage.<\/p>\n\n\n
