Helper Array Methodes

/*
For Each  - forEach accept a function iterator that loop through each item in an array
Example
*/

const numbers = [1,2,3,4,5];
numbers.forEach(element => {
    console.log(element);
});




/*
Map - Map will loop through each item of array, same like forEach but Map returns the value of the array.
*/

// square of the actual numbers
let doubleNumbers = numbers.map(element => Math.pow(element,2));
console.log(doubleNumbers);



/*
Find - find will return the record if a particular element is found in the array.
*/

const students = [
    { regNo: 192, name: "Abc" },
    { regNo: 1302, name: "bcd" }
]

let findStudent = students.find(element=> element.regNo === 192);
console.log(findStudent)



/*
Filter - Filter return array based on the boolean of the comparison
*/

let largeNumbers = numbers.filter(element => element>3);
console.log(largeNumbers);



/*
Some- some accept an iterator function that will return true or false

*/
const names = ["Alemran","Jimmy","Johnny"];
const newName = names.some(element => element.length < 3)
console.log(newName)


/*
Every - The every helper is used to find whether all the elements in a given list pass a specific condition
*/
const allname = names.every(element => element.length > 4)
console.log(allname)
