Array helpers, so you can get very fast your data from the array.
here an example array.
var exampleArray = [
{
id: 0,
name: 'John',
age: 93,
city: 'Patmos',
},
{
id: 1,
name: 'Peter',
age: 62,
city: 'Rome',
},
{
id: 2,
name: 'Luke',
age: 84,
city: 'Boeotia'
},
{
id: 2,
name: 'Paul',
age: 62,
city: 'Rome'
},
];
Sort an array with objects by the key of the object.
By default it is asc, and you can set desc as an optional value to the 2nd parameter.
exampleArray.multisort('age', 'desc');
[
{
id: 0,
name: 'John',
age: 93,
city: 'Patmos',
},
{
id: 2,
name: 'Luke',
age: 84,
city: 'Boeotia'
},
{
id: 1,
name: 'Peter',
age: 62,
city: 'Rome',
},
{
id: 2,
name: 'Paul',
age: 62,
city: 'Rome'
},
]
Filters the array for a given key and value.
If the 3th parameter is true, excluding a given key and value.
exampleArray.multifilter('age', '62');
[
{
id: 1,
name: 'Peter',
age: 62,
city: 'Rome',
},
{
id: 2,
name: 'Paul',
age: 62,
city: 'Rome'
},
]
exampleArray.multifilter('age', '62', '!=');
[
{
id: 0,
name: 'John',
age: 93,
city: 'Patmos',
},
{
id: 2,
name: 'Luke',
age: 84,
city: 'Boeotia'
},
]
exampleArray.multifilter('age', '62', '>');
[
{
id: 0,
name: 'John',
age: 93,
city: 'Patmos',
},
{
id: 2,
name: 'Luke',
age: 84,
city: 'Boeotia'
},
]
exampleArray.multifilter('age', '84', '<=');
[
{
id: 2,
name: 'Luke',
age: 84,
city: 'Boeotia'
},
{
id: 1,
name: 'Peter',
age: 62,
city: 'Rome',
},
{
id: 2,
name: 'Paul',
age: 62,
city: 'Rome'
},
]
exampleArray.multifilter('name', ['John', 'Peter']);
[
{
id: 0,
name: 'John',
age: 93,
city: 'Patmos',
},
{
id: 1,
name: 'Peter',
age: 62,
city: 'Rome',
},
]
Plucks the given keys from the array.
exampleArray.multikey(['name', 'age']);
[
{
name: 'John',
age: 93
},
{
name: 'Peter',
age: 62
},
{
name: 'Luke',
age: 84
},
{
name: 'Paul',
age: 62
},
]
Computes the intersection of arrays. Returns an array containing the values that are present in all the arrays.
If the 2nd parameter is true, the 1st parameter can contain multiple arrays.
var a = ['John', 'Peter', 'Luke'];
var b = ['Peter', 'Luke', 'Paul'];
var c = ['Peter', 'Luke', 'John'];
a.intersect(b);
['Peter', 'Luke']
a.intersect([b c], true);
['Peter', 'Luke']
Computes the difference of arrays. Compares the array values, and return all values from array a that arent present in array b.
If the 2nd parameter is true, it return all values that are not present in any of the arrays.
var a = ['John', 'Peter', 'Luke'];
var b = ['Peter', 'Luke', 'Paul'];
a.diff(b);
['John']
a.diff(b, true);
['John', 'Paul']
Removes duplicate values from an array. Takes the array and returns a new array without duplicate values.
var a = ['John', 'Peter', 'Luke', 'Peter', 'Luke', 'Paul'];
a.unique();
['John', 'Peter', 'Luke', 'Paul']
Only push the value to the array if the value doesnt exists in the array.
Returns the new length property of the object upon which the method was called.
var a = [];
a.pushIfNotExists('John');
['John']
a.pushIfNotExists('Peter');
['John', 'Peter']
a.pushIfNotExists('John');
['John', 'Peter']
The largest of the given numbers. If at least one of the arguments cannot be converted to a number, NaN is returned.
var exampleArray = [1,2,3];
exampleArray.max();
3
The smallest of the given numbers. If at least one of the arguments cannot be converted to a number, NaN is returned.
var exampleArray = [1,2,3];
exampleArray.min();
1
Get a random value of an array.
var exampleArray = [1,2,3];
exampleArray.min();
e.g. 2
The summ of all values.
var exampleArray = [1,2,3];
exampleArray.summ();
6
Get the average of all values.
var exampleArray = [1,2,3];
exampleArray.average();
