# LODASH CLONE
**This library is just for demonstration my coding skill and a utility that i use in my own projects.it is heavily inspired from Lodash Library, but entire implementation by me **
Using the library:
**DOCS:**
_Using Array **reduce**_
```js
ArrMan.reduce([1, 2], function(sum, n) {
return sum + n;
}, 0);
// => 3
ArrMan.reduce({ 'a': 1, 'b': 2, 'c': 1 }, function(result, value, key) {
(result[value] || (result[value] = [])).push(key);
return result;
}, {});
// => { '1': ['a', 'c'], '2': ['b'] } (iteration order is not guaranteed)
```
_Using Array **reduceRight**_
```js
var array = [[0, 1], [2, 3], [4, 5]];
ArrMan.reduceRight(array, function(flattened, other) {
return flattened.concat(other);
}, []);
// => [4, 5, 2, 3, 0, 1]
```
_Using Array **forEach**_
```js
ArrMan.forEach([1, 2], function(value) {
console.log(value);
});
// => Logs `1` then `2`.
ArrMan.forEach({ 'a': 1, 'b': 2 }, function(value, key) {
console.log(key);
});
```
_Using Array **forEachRight**_
```js
ArrMan.forEachRight([1, 2], function(value) {
console.log(value);
});
// => Logs `2` then `1`
```
_Using Array **map**_
```js
function square(n) {
return n * n;
}
ArrMan.map([4, 8], square);
// => [16, 64]
ArrMan.map({ 'a': 4, 'b': 8 }, square);
// => [16, 64] (iteration order is not guaranteed)
var users = [
{ 'user': 'barney' },
{ 'user': 'fred' }
];
ArrMan.map(users, 'user');
// => ['barney', 'fred']
```
_Using Array **filter**_
```js
var users = [
{ 'user': 'barney', 'age': 36, 'active': true },
{ 'user': 'fred', 'age': 40, 'active': false }
];
ArrMan.filter(users, function(o) { return !o.active; });
// => objects for ['fred']
ArrMan.filter(users, { 'age': 36, 'active': true });
// => objects for ['barney']
ArrMan.filter(users, ['active', false]);
// => objects for ['fred']
ArrMan.filter(users, 'active');
// => objects for ['barney']
```
_Using Array **reject**_
```js
var users = [
{ 'user': 'barney', 'age': 36, 'active': false },
{ 'user': 'fred', 'age': 40, 'active': true }
];
ArrMan.reject(users, function(o) { return !o.active; });
// => objects for ['fred']
ArrMan.reject(users, { 'age': 40, 'active': true });
// => objects for ['barney']

];
ArrMan.find(users, function(o) { return o.age < 40; });
// => object for 'barney'
ArrMan.find(users, { 'age': 1, 'active': true });
// => object for 'pebbles'
ArrMan.find(users, ['active', false]);
// => object for 'fred'
ArrMan.find(users, 'active');
// => object for 'barney'
```
_Using Array **every**_
```js
ArrMan.every([true, 1, null, 'yes'], Boolean);
// => false

{ 'user': 'barney', 'age': 36, 'active': false },
{ 'user': 'fred', 'age': 40, 'active': false }
];
ArrMan.every(users, { 'user': 'barney', 'active': false });
// => false
ArrMan.every(users, ['active', false]);
// => true

// => false
```
_Using Array **some**_

];
ArrMan.some(users, { 'user': 'barney', 'active': false });
