Conditionals

While programming, most of the time a decision needs to be made, therefore we have the conditional tools, that help ups model such decisions

If and Else

if (*some condition is true*){
  // do this code
} else if (*other condition*) {
 // Otherwise, do this code if match the other condition
} else { 
 // Otherwise, do this code 
}

Sample

var valueA = 1;
var valueB = 10;

if (valueA > valueB){
 console.log("The "+valueA+" is greater than "+valueB);
}else if (valueA == valueB){
 console.log("The "+valueA+" is aqual to : "+valueB);
} else{ 
 console.log("The "+valueA+" is minor than "+valueB); 
}

Binary AND     &&

Evaluates to true if both values at the left and right are true, otherwise will evaluate to false

Sample

var valueA = true;
var valueB = false;

if(valueA && valueB){
 console.log("Both values are true");
}else{
 console.log("");
}

Binary OR     ||

Evaluates to true if any of the two values at the left and right are true.

Sample

var valueA = true; 
var valueB = false; 

if(valueA || valueB){ 
 console.log("Any Both values are true"); 
}else{ 
 console.log("Both values are false"); 
}
