Can a while loop have two conditions Javascript?

It can consist of multiple sub-statements i.e. there can be multiple conditions. For as long as condition evaluates to true , the code written inside the while block keeps on executing. As soon as condition evaluates to false , the loop breaks.

Can you put multiple conditions in a while loop?

Using multiple conditions As seen on line 4 the while loop has two conditions, one using the AND operator and the other using the OR operator. Note: The AND condition must be fulfilled for the loop to run. However, if either of the conditions on the OR side of the operator returns true , the loop will run.

Can you have multiple conditions in an if statement Javascript?

We can also write multiple conditions inside a single if statement with the help of the logical operators && and | | . The && operators will evaluate if one condition AND another is true. Both must be true before the code in the code block will execute. Both conditions prove true so the code in the code block executes.

How do you write an if statement with multiple conditions?

When using multiple conditions, we use the logical AND && and logical OR || operators. Note: Logical AND && returns true if both statements are true….Java if Statement

  1. Less than – a < b.
  2. Less than or equal to – a <= b.
  3. Greater than – a > b.
  4. Greater than or equal to – a >= b.
  5. Equal to – a == b.
  6. Not Equal to – a != b.

How do you use multiple conditions in a for loop?

Note: You cannot use multiple test conditions separated by comma, you must use logical operator such as && or || to join conditions. 3. It has two variables in increment part.

Can you use && in a while loop?

The while loop should keep looping until both conditions are true, but it stops when only one becomes true.

How do you do multiple conditions in a for loop?

I generally use ‘&&’ or ‘||’ to separate multiple conditions in a for loop, but this code uses commas to do that. Surprisingly, if I change the order of the conditions the output varies.

How does while loop start in JavaScript?

First, we set a variable before the loop starts (var i = 0;) Then, we define the condition for the loop to run. As long as the variable is less than the length of the array (which is 4), the loop will continue. Each time the loop executes, the variable is incremented by one (i++)

Why do we use while loops in JavaScript?

The purpose of a while loop is to execute a statement or code block repeatedly as long as an expression is true. Once the expression becomes false, the loop terminates.

How do you optimize multiple if else statements in Java?

Java (optimization 28) optimizing if else writing

  1. Optimization scheme 1: return in advance to remove unnecessary else.
  2. Optimization scheme 2: use conditional binomial operator.
  3. Optimization scheme 3: use enumeration.
  4. Optimization scheme 4: merge condition expression.
  5. Optimization scheme 5: using Optional.

How many times is a Do While loop guaranteed to loop?

So the do while loops runs once and it is guaranteed.

When to use a while loop instead of a for loop?

A while loop is used to when we don’t know how many times the loop will be executed, but know that the loop should execute as long as some condition is true. But this is not a rule and a for loop can be substituted for a while loop and vice versa. Here the initialization, condition and increment are grouped together at one place.

When to use while condition in Java stack overflow?

If your code, if the user enters ‘X’ (for instance), when you reach the while condition evaluation it will determine that ‘X’ is differente from ‘n’ (nChar != ‘n’) which will make your loop condition true and execute the code inside of your loop. The second condition is not even evaluated. Thanks for contributing an answer to Stack Overflow!

How to write multiple conditions in a while loop in C?

Move the small box close to the left side of the big box. Draw the line with the red color. Move the line down 1/2 inch. Move the small box down 1/2 inch. If the small box is still in the big box, repeat. Draw the line with the red color.

How to use nested if conditional statement in JavaScript?

This is possible by using the nested if statement supported by javascript. In this article, we will learn how we can use nested if conditional statement to check the conditions within other conditions.
