Day 1: If Else Statements
Explanation
If/else statements are conditional statements that are used to perform different actions based upon different conditions.
If/else statements
Here's a useful video on the topic:
The if statement executes a block of code if the specified condition is true:
*Syntax*
if (condition) {
//block of code
}
The else statement executes a block of code if all of the conditions are false:
*Syntax*
if (condition) {
//block of code if condition is true
} else {
//block of code if none of the condition(s) is true.
}
The else if statement executes a block of code if its condition is true, and the previous conditions are false:
*Syntax*
if (condition) {
//block of code if condition is true
} else if (condition_2) {
//block of code if condition is false and condition_2 is true.
} else if (condition_3) {
//block of code if condition is false and condition_2 is false and condition_3 is true.
} else {
//block of code if none of the condition(s) is true.
}
Example
if (time < 12) {
console.log("Good morning");
} else if (time < 14) {
console.log("Good Afternoon");
} else {
console.log("Good evening");
}

- FF
if marks
is less than or equal to .
Note
Do not declare the variable marks
. It is declared inside our code checker.
Use console.log
for printing statements to the console.
