function

htmlentitiesEncode

core.js:40

Equivalent of php function htmlentities()

function MMO.core.htmlentitiesEncode(text)

Namespace: MMO.core

text
returns	`*`

function

htmlentitiesDecode

core.js:48

Decode html entities encoded with php function htmlentities() or js function MMO.core.htmlentitiesEncode()

function MMO.core.htmlentitiesDecode(text)

Namespace: MMO.core

text

function

preventPropagation

core.js:59

Alias to stop event propagation

function MMO.core.preventPropagation(e, allow_link = false)

Namespace: MMO.core

e	`Event`
allow_link = false
returns	`Function`

function

isEmpty

core.js:77

Check if object is empty

function MMO.core.isEmpty(obj)

Namespace: MMO.core

obj	`Object`
returns	`Boolean`

function

isEqual

core.js:93

Check if 2 values are equal (deep)

function MMO.core.isEqual(a, b)

Namespace: MMO.core

a
b
returns	`Boolean`

function

isSimilar

core.js:165

Test whether b is "contained in" a (a one-way, loose comparison).

function MMO.core.isSimilar(a, b)

Namespace: MMO.core

Unlike `MMO.core.isEqual` this is NOT symmetric: `a` may hold more than `b`. - primitives: compared loosely (`==`), so `1` and `'1'` are similar - objects/Maps: every key of `b` must be present in `a` and similar; extra keys in `a` are ignored - arrays: `b` must be a SUBSEQUENCE of `a`, order preserved

a	`*`	the larger value
b	`*`	the value to look for inside `a`
returns	`boolean`

isSimilar({a:1, b:2}, {a:1}) // true -- subset isSimilar([1,2,3], [1,3]) // true -- subsequence isSimilar([1,2,3], [3,1]) // false -- wrong order

function

compare

core.js:207

Compare the two parameters

function MMO.core.compare(a, b)

Namespace: MMO.core

a
b
returns	`null` \| `int`	null if comparison cannot be done, 0 if similar, -1 if inferior, 1 if superior.

function

compareDescending

core.js:223

function MMO.core.compareDescending(a, b)

Namespace: MMO.core
See: MMO.core.compare with the operands swapped, for a descending sort.

a	`*`
b	`*`
returns	`?number`

function

isUnique

core.js:232

Check if an array has only unique items

function MMO.core.isUnique(array)

Namespace: MMO.core

array	`Array`
returns	`Boolean`

function

isSimpleObject

core.js:250

Test whether a value is a plain data container rather than a class instance.

function MMO.core.isSimpleObject(obj, allowArray = true)

Namespace: MMO.core

This is what decides whether `MMO.core.Map#set` converts a value into a nested Map.

obj	`*`
allowArray = true	`boolean`	count arrays as simple objects
returns	`boolean`

function

isSameArray

core.js:263

Test if two arrays hold the same values, ignoring their order.

function MMO.core.isSameArray(a, b)

Namespace: MMO.core

Values are compared with `Array.includes` (strict equality, `NaN` included). NOTE: duplicates are not accounted for, `[1,1]` and `[1,2]` both "contain" `1`, but they differ in length so the check still rejects them.

a	`Array`
b	`Array`
returns	`boolean`

function

watch

core.js:281

Watch for a change on a proerty's value Redefine object's property with a getter and a setter.

function MMO.core.watch(obj, key, handler)

Namespace: MMO.core

NOTE : To remove the watch, assign MMO.core.UNWATCH_EVENT to the property. It will restore the previous property descriptor ex: MMO.core.watch(obj, 'a'); ...; obj.a = MMO.core.UNWATCH_EVENT;

obj	`Object`	the object
key	`string`
handler	`Function`	function(value, key, old_value) called with this = obj

function

unwatch

core.js:344

Unwatch an object's property ONLY set the value to MMO.core.UNWATCH_EVENT.

function MMO.core.unwatch(obj, key)

Namespace: MMO.core

obj	`Object`	the object
key	`string`
returns	`Boolean`	true if the property was watched

function

link

core.js:365

Set a link to another object's property as a property To remove the link just delete the property

function MMO.core.link(obj, key, obj2, key2)

Namespace: MMO.core

obj	`Object`	the object
key	`string`
obj2	`Object`	the object to link to
key2	`string`	the object's property to link to

function

getter

core.js:381

Create a function that reads an object's property when called.

function MMO.core.getter(obj, key)

Namespace: MMO.core

Useful as an argument of `MMO.core.linkFn`

obj	`Object`
key	`string`
returns	`Function`	function(): *

function

linkFn

core.js:393

Set a function as an object's property To remove the function just delete the property

function MMO.core.linkFn(obj, key, fn, ...args)

Namespace: MMO.core

obj	`Object`	the object
key	`string`
fn	`Function`	function(...args): value
...args	`...?`	a list of values\|function to use to call the function.

Namespace: MMO.core

map	`Object`	modified in place
cmpFn	`?Function`	function(keyA, keyB): number, defaults to Array.sort's order
returns	`Object`	the same object
