Trying to grasp the concepts of functions and methods has been a challenge for me. I often find myself confused about when, where, and how to use return statements in different situations. To illustrate this confusion, let's take a look at two code snippets from unrelated operations.
Code 1:
var john = {
fname : 'John',
mass : 45,
age : 24,
height : 2,
calculateBMI : function(){
this.bmi = this.mass/(this.height * this.height);
return this.bmi;
}
Code 2:
var adi ={
fName : "adi",
bills : [124,48,268,180,242],
calculateTips : function(){
this.tips =[];
this.totalValue = [];
for(var i=0; i<this.bills.length;i++){
var percentage;
var bill = this.bills[i]
if(bill<50){
percentage = 0.2;
}else if(bill>=50 && bill<200){
percentage = 0.15;
}else{
percentage = 0.1;
}
this.tips[i] = percentage * bill;
this.totalValue[i] = bill + bill * percentage;
