# HashMap (scripting commands)

- [+](../../commands/~2B.md): Add two Numbers, concatenate two Arrays or two Strings, or create a copy of an Array or HashMap.
- [apply](../../commands/apply.md): Applies the given code to each element of the given data structure and collects the results in an array.
- [count](../../commands/count.md): Can be used to count:
- [createHashMap](../../commands/createHashMap.md): Creates a new empty HashMap.
- [createHashMapFromArray](../../commands/createHashMapFromArray.md): Creates a new HashMap and initializes it from a key-value pair array
- [createHashMapObject](../../commands/createHashMapObject.md): Create a HashMap with an Object-Oriented Programming behaviour. Inside a object, Methods (if they are called correctly, either by engine or via call - Syntax 3) will have the objects instance inside the _self variable.
- [deleteAt](../../commands/deleteAt.md): Removes array element at the given index and returns removed element (modifies the original array, just like resize or set).
- [forEach](../../commands/forEach.md): Executes the given command(s) on every item of an Array or a HashMap.
- [get](../../commands/get.md): Retrieves a value out of a HashMap after looking it up by its key.
- [getOrDefault](../../commands/getOrDefault.md): Retrieves a value out of a HashMap after looking it up by its key. When the HashMap doesn't contain the key, the default value is returned
- [getOrDefaultCall](../../commands/getOrDefaultCall.md): Retrieves a value from the HashMap for the given 'key', executes given 'code' if key was not found and returns result. Additionally sets key to the code result value if set is true.
- [hashValue](../../commands/hashValue.md): Processes provided value's hash, and encodes it using Base64. The hash algorithm is FNV-1A 64bit.
- [in](../../commands/in.md): Checks whether value is in array, unit is in vehicle, position is inside location or ANSI string is part of other ANSI string. If Unicode support is desired, see forceUnicode.
- [insert](../../commands/insert.md): Inserts multiple values into Array/String/HashMap. The String variant also supports forceUnicode. In the event of a HashMap, values, if they already exist, are replaced.
- [keys](../../commands/keys.md): Retrieves a list of all keys in a HashMap.
- [merge](../../commands/merge.md): Merges two HashMaps.
- [set](../../commands/set.md): Changes the element at the given zero-based index of the array.
- [toArray](../../commands/toArray.md): Converts the supplied String into an Array of Numbers. The numbers in the created array are the decimal Unicode representations of characters.
- [values](../../commands/values.md): Returns all values stored in the given HashMap. The order of the returned Array corresponds to the order of the Array returned by the keys command.
