The continue statement is used inside loops (like for, while, or do-while) to skip the rest of the code inside the loop for the current iteration and move on to the next iteration. It is particularly useful when you want to skip certain iterations based on a specific condition. Here are some key concepts related to JavaScript loops
1) Types of Loops:
for Loop:
The for loop is commonly used when the number of iterations is known.
while Loop:
The while loop is used when the number of iterations is not known in advance, and it continues as long as a specified condition evaluates to true.
do-while Loop:
Similar to the while loop, but the condition is checked after the block of code is executed. This ensures that the code inside the loop will be executed at least once.
2) Loop Execution:
T he for loop is generally used when the number of iterations is known in advance. The while loop is suitable when the number of iterations is not known initially, and the loop continues as long as a specified condition is true.
The do-while loop is similar to the while loop but guarantees that the code inside the loop will be executed at least once because the condition is checked after the loop body.
3)Loop Control Statements:
break Statement:
Used to terminate the loop prematurely.
continue Statement:
Skips the rest of the loop code and continues with the next iteration.
These are the basic constructs for creating loops in JavaScript. The appropriate loop to use depends on the specific requirements of your code.
4) Infinite Loops:
Be cautious about creating infinite loops that never terminate. Ensure that there’s a condition that will eventually be false.
5) Looping Arrays:
Loops are commonly used to iterate over arrays, allowing you to process each element in the array.
1) Nested Loops:
You can have loops inside other loops, known as nested loops, for more complex iterations.
