5.4.1. if Statements

/*The condition in an if statement can be any boolean expression, 
such as name === 'Jack' or points > 10 (here, name and points are 
variables). Additionally, the code block associated with a conditional 
can be of any size. This conditional has a code block with two lines of 
code:*/

if (num % 2 === 0 && num > 3) {
   console.log(num, "is even");
   console.log(num, "is greater than 3");
}

/*While not required, the code within a conditional code block is 
typically indented to make it more readable. Similarly, it is a common
convention to place the opening { at the end of the first line, and the 
closing } on a line of its own following the last line of the code 
block. You should follow such conventions, even though ignoring them 
will not create an error.*/

5.4.3. else if Statements¶

/*Regardless of the complexity of a conditional, no more than one of 
the code blocks will be executed.*/

let x = 10;
let y = 20;

if (x > y) {
   console.log("x is greater than y");
} else if (x < y) {
   console.log("x is less than y");
} else if (x % 5 === 0) {
   console.log("x is divisible by 5");
} else if (x % 2 === 0) {
   console.log("x is even");
}
//x is less than y

/*Even though both of the conditions x % 5 === 0 and x % 2 === 0 
evaluate to true, neither of the associated code blocks is executed. 
When a condition is satisfied, the rest of the conditional is 
skipped.*/

5.4.3. else if Statements¶

/*If-else statements allow us to construct two alternative paths. 
A single condition determines which path will be followed. We can 
build more complex conditionals using an else if clause. These allow 
us to add additional conditions and code blocks, which facilitate more 
complex branching.*/

let x = 10;
let y = 20;

if (x > y) {
   console.log("x is greater than y");
} else if (x < y) {
   console.log("x is less than y");
} else {
   console.log("x and y are equal");
}
//x is less than y
