Decision Making and Loops in JavaScript

There are situations when we want to run the code at different conditions, such as, if one condition applies run a particular code, if another condition applies another code is run. This is prioritized with "if" and "else if" conditionals as follows:

function getColor(phrase){
   if (phrase === "stop"){
       console.log("red");
   } else if (phrase === "slow"){
       console.log("yellow");
   } else if (phrase === "go"){
       console.log("green");
   } else {
       console.log("purple");
   }
}

We can run codes in multiple loops if we want to with the help of loops. With loops, our code runs until a certain condition is satisfied such as:

for (let i = 25; i >= 0; i-=5) {
    console.log(i)
}
