JS Loops
JavaScript Loop Structures
JavaScript loops include for, while, and do-while, with break/continue.
Introduction to JavaScript Loops
Loops are essential in programming for executing a block of code repeatedly. JavaScript provides several loop constructs: for, while, and do-while. Each has unique uses and advantages depending on the scenario.
The 'for' Loop
The for loop is ideal when you know how many times you need to iterate. It consists of three parts: initialization, condition, and increment/decrement.
The 'while' Loop
The while loop is used when the number of iterations is not known beforehand. It continues as long as the specified condition evaluates to true.
The 'do-while' Loop
The do-while loop is similar to the while loop, but it guarantees at least one iteration because the condition is evaluated after the loop body.
Using 'break' and 'continue'
The break statement exits the loop immediately, while the continue statement skips the current iteration and moves to the next one.
