JS CONDITIONAL STATEMENTS

Question 1

IF

Answer 1

if (condition) {
CODE TO BE RUN GOES HERE;
}

// Code inside brackets will run if the condition/value is true (NOTE: Remember to use parentheses () around the condition/value)

Question 2

IF and ELSE

Answer 2

if (condition) {
  CODE TO BE RUN GOES HERE;
} else {
  CODE TO BE RUN GOES HERE;
}

// Code in ELSE brackets runs when the IF condition/value is NOT True. Also, when the IF condition/value is True the code in the IF brackets will run but the code in the ELSE brackets will NOT run.

Question 3

IF and ELSE IF

Answer 3

if (condition) {
CODE TO BE RUN GOES HERE;
}else if (condition){
CODE TO BE RUN GOES HERE;
}
Code in ELSE IF brackets runs if previous condition(s) are NOT true and the condition for that ELSE IF is True.
// NOTE: While there can only be a single IF and a single ELSE in a conditional statement, there is no limit to the amount of ELSE IFs that can be used in a conditional statement.

Question 4

IF, ELSE IF, and ELSE

Answer 4

if (condition) {
  CODE TO BE RUN GOES HERE;
} else if (condition) {
  CODE TO BE RUN GOES HERE;
} else {
  CODE TO BE RUN GOES HERE;
}

// Code in ELSE brackets will always run as long as previous conditions are False (NOTE: ELSE does have a condition that needs to be met for it to run)

Question 5

Nested Conditional Statements

Answer 5

if (true) {
  console.log("Hello");
  if (false) {
    console.log("Hi");
  }
} else {
  console.log("Goodbye");
}

// A conditional statement can be nested inside another conditional statement
// In this example the console.log("Hi") will only run when both the very first IF condition is True and the nested IF condition is True
