conditional Statements in Js

Conditional Statements allow us to perform different actions for different conditions.

    if
    if...else
    if...else if...else
    switch
    ternary (? :)

If:
Use if to specify a code block to be executed, if a specified condition is true.

if(conditon)
{
   //executed the code block
}

The else Statement:

Use else to specify a code block to be executed, if the same condition is false.
Syntax

if (condition) {
  // code to execute if the condition is true
} else {
  // code to execute if the condition is false
}

The else if Statement:

Use else if to specify a new condition to test, if the first condition is false.
Syntax:

if (condition1) {
  // code to execute if condition1 is true
} 
else if (condition2) {
  // code to execute if the condition1 is false and condition2 is true
} 
else {
  // code to execute if the condition1 is false and condition2 is false
}

The switch Statement:
switch executes the code blocks that matches an expression.

switch is often used as a more readable alternative to many if...else if...else statements, especially when dealing with multiple possible values.if break is not here in the every case they continue the next case is printed and after the break is executed the block code

Syntax

switch(expression) {
  case x:
    // code block
    break;
  case y:
    // code block
    break;
  default:
    // code block
}

Ternary Operator (? :)

Use (? :) (ternary) as a shorthand for if...else.
Example

condition ? expression1 : expression2
