exercise 1:
let names = (...person) =>`String [${person.join("], [")}] => Done !`;
console.log(names("Osama", "Mohamed", "Ali", "Ibrahim"));

[whitepearl]

exercise 2:
let myNumbers = [20, 50, 10, 60];
let calc =(one, two, ...nums)=> one + two +nums[0];

console.log(calc( 10, myNumbers [0], myNumbers[1]));

[xvax]

let names=(...input ) =>{ return `String [${input.join("], [")}] => Done !`};


console.log(names("A", "B", "C", "d", "e"));

[ilyesonline]

thanks teacher for your efforts, this is the answer =>

/* Chellange 01 Start */

let names = (...name) => `String [${name.join("], [")}] => Done !`;

console.log(names("Osama", "Mohamed", "Ali", "Ibrahim"));
// String [Osama], [Mohamed], [Ali], [Ibrahim] => Done !

/* Chellange 01 End */

/* */

/* Chellange 02 Start */

let myNumbers = [20, 50, 10, 60];

function calc(one, two, ...nums) {
return one + two[0] + nums[0][1];
}

console.log(calc(10, myNumbers, myNumbers))

/* Chellange 02 End */

Exercise 2 :
let myNumbers = [20, 50, 10, 60];

let calc = (one, tow, ...nums) => one + tow + nums[0];

console.log(calc(10, myNumbers[0], myNumbers[1])) // 80

جزاك الله خيرا يا بشمهندس و شكرا على هذا المجهود الرائع
زادك الله علمًا ورفعك قدرًا و جعل هذا العلم النافع فى ميزان حسناتك💗

tsk 2 :
let myNumbers = [20, 50, 10, 60];
let calc = function (one, two, ...nums) {
return one + two + nums.shift(); };

console.log(calc(10, myNumbers.shift(), myNumbers.shift())); // 80

[engmahrouselsayed]

أسأل الله العظيم ان يجزيك كل الخير على المجهود الرائع دة ويجعله في موازين حسناتك

[wajdwael]

// Challenge two

let myNumbers = [20, 50, 10, 60];
let calc = (one, two, ...nums) => one + two + +nums;
console.log(calc(10, myNumbers[1], myNumbers[0])); // 80

" Adding + before the ${nums} transforms it to a number"

[czodrdp]

console.log("Exam 3");
let cla= (num1, num2, ...num3) => num1+num2+Number(num3);
console.log(cla(10, 50, 20)) ;

[FartakaTechnology]

عظمة كالعادة يا بشمهندس
ربنا يوفقك ويجزاك خير علي الي بتقدمه للناس من علم بكل حب
هفضل احطلك الكومنت دا علي كل فيديو اذاكره في الكورس دا لحد ما يخلص كله

[muntder]

التحدي الثاني :
let myNumbers = [20, 50, 10, 60];

let calc = (one, two, ...nums) => ((two - one) + (nums[0]-nums[1]))*4;

console.log(calc(10, 20, 60, 50));

[loverpoet]

let numbers = [20, 50, 10, 60];
let calc = (one, two, ...nums) => (one + two + +nums);
console.log(calc(10, 20, 50)); // = 80

[jimmy]

let myNumbers =[20, 50, 10, 60]

let calc = ( one, two, ...nums)=> one + two + +nums

console. log(calc(10, myNumbers[1], myNumbers[0])); // 80

[walidouzzane]

// Challenge 2
// Arrow Function :


let myNumbers = [20, 50, 10, 60];

let calc = (one, two, ...nums) => {
let result = one+two
for (let i =0; i<nums.length; i++){
result += nums[i]
};
return result
}

// Regular Function:

let calc = function(one, two, ...nums){
let result = one+two
for(let i = 0; i < nums.length; i++){
result += nums[i]
}
return result
}

console.log(calc(10, myNumbers.shift(), myNumbers.shift())); // 80

شرحك ممتع حبيبي, ربنا يحشرك مع رسول الله, فهمت الدرس بنسبة 100% انتي ملهم ما شاء الله عليك

[AbdalrhmanForProgramming]

التحدي الثاني
let numbers = [20, 50, 10, 60];

let calc = (one, tow, ...nums) => console.log(one+one + tow + nums.length*one);
console.log(calc(10, 50, 20));
//80




function calc(one, tow, ...nums)
{
console.log(one + one + tow + nums.length * one);
}
console.log(calc(10, 50, 20));
//80

[habibamohamedelsayed]

challenge 2
let calc=(one, two, ...numbers)=>{
one=myNumbers[Number(false)]
two=myNumbers[Number(true)]

console.log(one+two+three)}

[envqemp]

exercise 2



let numbers = [20, 50, 10, 60];

let calc = function (one, two, ...nums) {
return one + two - (-nums);
}

console.log(calc(10, 20, 50));

// CHALENGE 01 :
console.log("First Chalenge 01 :")

let names = (...names) => `String [${names.join("], [")}] => Done!`;

console.log(names("USA", "CANADA", "UK", "AUSTRALIA"));


// chanlenge 02 :
console.log("Second chalenge 02 :")

let myNumbers = [20, 50, 10, 60];

let calc = (one, two, ...nums) => `${one + two + nums[0]}`;

console.log(calc(10, myNumbers[2], myNumbers[3]));

thank you so much ELZERO you are the best 😇
