Now lets see Loops and conditions in JavaScript

…

IF:

Syntax:
if (expression) {
   Statement(s) to be executed if expression is true
}
Example:
let x = 5; 
if(x>4){
    document.write(x)
  }

ELSE:

Syntax:
if (expression) {
   Statement(s) to be executed if expression is true
} else {
   Statement(s) to be executed if expression is false
}
Example:
let x = 5; 
if(x>4){
    document.write(x)
  } else{
document.write("No");
}

ELSE IF:

Syntax:
if (expression 1) {
   Statement(s) to be executed if expression 1 is true
} else if (expression 2) {
   Statement(s) to be executed if expression 2 is true
} else if (expression 3) {
   Statement(s) to be executed if expression 3 is true
} else {
   Statement(s) to be executed if no expression is true
}
Example:
let x = 2; 
if(x>4){
    document.write(x)
  } else if (x>1){
document.write("No");
} else{
document.write("maybe")
}

Switch Case:

Syntax:
switch (expression) {
   case condition 1: statement(s)
   break;
   
   case condition 2: statement(s)
   break;
   ...
   
   case condition n: statement(s)
   break;
   
   default: statement(s)
}
Example:
let a =1
let b= 4…
