syntax: for(statement 1; statement 2; statement 3){
  //code block to be executed
}     
     
//Statement 1 initializes the variable used in the loop (let i = 0). Many values can be initiated (separated by coma)
     
//Statement 2 evaluates the condition of the inital value. If it returns true, the loop will start over again, if it returns false, the loop wil end
     
//Statement 3 increments the value of the inital variable. It can do anything like negative increment (i--), and positive increment (i = i +15)

//The JS "for in" statement loops through the properties of an Object:

//Syntax
for (key in object){
  //code block to be executed
}

const person = {first_name: "John", last_name: "Doe", age:25};

let text = "";
for (let x in person) {
  text += person[x]
}

//John Doe 25

// Example explained
-   The for in loop iterates over a person object
-   Each iteration returns a key (x)
-   The key is used to access the value of the key
-   The value of the key is person[x]

//For in over arrays
for (variable in array){
  code
}

const numbers = [45,4,9]

let txt = "";
for (let x in numbers){
  txt += numbers[x]
}

// 45
//  4
//  9

//NOTE: It is better to use a "for" loop, a "for of" loop, or "Array.forEach()" when the order matters


///Array.forEach()
//forEach() method calls a function (a callback function) once for each array element
const numbers = [45,4,9]

let txt = "" (or let arr = []);
numbers.forEach(myFunction);

function myFunction(value, index, array){
  txt += value;
}

// Setup
const myArray = [];

for(let i = 1;i<10; i +=2){
  myArray.push(i)
}

//While loop loops through a block of code as long as a specified condition is true

//Syntax
while (condition){
  //code block to be executed
}

while (i < 10){
  text += "The number is" +i;
ii+

//Very simple, given an integer or a floating-point number, find its opposite.

//Timmy & Sarah think they are in love, but around where they live, they will only know once they pick a flower each. If one of the flowers has an even number of petals and the other has an odd number of petals it means they are in love.

//Write a function that will take the number of petals of each flower and return true if they are in love and false if they aren't.

    if (flower1%2==0&&flower2%2!==0) {
        return true;
    }else if(flower1%2!==0&&flower2%2==0){
        return true;

//  Best practice
//function lovefunc(flower1, flower2){

//Write a function to convert a name into initials. This kata strictly takes two words with one space in between them.
//The output should be two capital letters with a dot separating them.
