In JavaScript, while and if statements serve different purposes.
The while statement repeatedly executes a statement while a specified condition is true. It is used for looping, allowing you to execute a block of code multiple times as long as a condition remains true. The syntax for a while loop is as follows:
while (condition) {
// code to be executed
}
The condition is evaluated before the loop starts, as well as each time the loop is executed. The loop continues as long as the condition remains true.
The if statement, on the other hand, executes a statement if a condition is true. It is used for conditional execution, allowing you to execute a specific block of code only if a certain condition is met. The syntax for an if statement is as follows:
if (condition) {
// code to be executed if condition is true
}
The condition is evaluated once, and if it is true, the code block within the if statement is executed. If the condition is false, the code block is skipped.
In conclusion, while loops are used for repeated execution of code, while if statements are used for conditional execution of code.
