# Jecs
Jecs. Just an Entity Component System.
## Properties
### World
```luau
jecs.World: World
```
### Wildcard
### z<>
## Functions
### pair()
```luau
function jecs.pair(
first: Entity, -- The first element of the pair, referred to as the relationship of the relationship pair.
object: Entity, -- The second element of the pair, referred to as the target of the relationship pair.
): number -- Returns the Id with those two elements
```
::: info
Note that while relationship pairs can be used as components, meaning you can add data with it as an ID, however they cannot be used as entities. Meaning you cannot add components to a pair as the source of a binding.

For example, a Health type should be created using this.

### get()
```luau
function World:get(
entity: Entity, -- The entity
...: Entity<T> -- The types to fetch
): ... -- Returns the component data in the same order they were passed in
```
Returns the data for each provided type for the corresponding entity.
:::
### add()
```luau
function World:add(
entity: Entity, -- The entity
id: Entity<T> -- The component ID to add
): ()
```
Adds a component ID to the entity.
This operation adds a single (component) id to an entity.
::: info
This function is idempotent, meaning if the entity already has the id, this operation will have no side effects.
:::
### set()
```luau
function World:set(
entity: Entity, -- The entity
id: Entity<T>, -- The component ID to set
data: T -- The data of the component's type
): ()
```
Adds or changes the entity's component.
### query()
```luau
function World:query(
...: Entity<T> -- The component IDs to query with. Entities that satifies the conditions will be returned
): Query<...Entity<T>> -- Returns the Query which gets the entity and their corresponding data when iterated
```
Creates a [`query`](query) with the given component IDs.
Example:
::: code-group
```luau [luau]
for id, position, velocity in world:query(Position, Velocity) do
-- Do something
end
```
```ts [typescript]
for (const [id, position, velocity] of world.query(Position, Velocity) {
// Do something
}
```
