In the logical AND ( && ) operator, if both conditions are true , then the if block will be executed. If one or both of the conditions are false , then the else block will be executed.
JavaScript contains conditional statements like if-else , switch cases , etc. These statements are conditional and used to check whether the given condition is true or not; for this, we use OR || and && operators.
You can use the logical AND (&&) and logical OR (||) operators to specify multiple conditions in an if statement. When using logical AND (&&), all conditions have to be met for the if block to run.
Using either “&&” or “||” i.e. logical AND or logical OR operator or combination of can achieve 3 conditions in if statement JavaScript.
Simply use the logical "OR" operator, that is ||.
if (A || B)
Worth noting that || will also return true if BOTH A and B are true.
In JavaScript, if you're looking for A or B, but not both, you'll need to do something similar to:
if( (A && !B) || (B && !A) ) { ... }
Use the || operator.
if (A || B) { do something }
|| is the or operator.
if(A || B){ do something }
here is my example:
if(userAnswer==="Yes"||"yes"||"YeS"){
console.log("Too Bad!");
}
This says that if the answer is Yes yes or YeS than the same thing will happen
