An array-manipulating typescript/javascript class with sorting methods
An array-manipulating TypeScript/JavaScript class with methods that change
the order of the array items.
constructor(data? = []) // 'data' is assigned to this.data .
You can reset the array by accessing the class .data property:
this.data = [1,2,3,4];
data : any[] // the actual arrayclassName : string (read-only)
ts
alphabetize(): this;
// No item in this.data gets modified, but each is treated as a string
// during the sorting.
numbersAscending(): this;
// If not all items in this.data are of type 'number', it triggers error.
numbersDescending(): this;
// If not all items in this.data are of type 'number', it triggers error.
reverse(): this;
shuffle(): this;
// randomizes the order of items.ts
protected _createGetterAndOrSetterForEach(

/*********************
Use this method when you have a bunch of properties that need getter and/or
setter functions that all do the same thing. You pass in an array of string
names of those properties, and the method attaches the same getter and/or
setter function to each property.
IGetterSetterConfiguration is this object:
{
get_setterFunction?: (
propertyName: string, index?: number, propertyNames?: string[]
) => Function,
// get_setterFunction takes the property name as first argument and
// returns the setter function. The setter function must take one
// parameter and return void.
get_getterFunction?: (
propertyName: string, index?: number, propertyNames?: string[]
) => Function
// get_getterFunction takes the property name as first argument and
// returns the getter function. The getter function must return something.
}
*********************/
protected _returnThis_after(voidExpression: any) : this
// voidExpression is executed, then function returns this.
// Even if voidExpression returns something, the returned data isn't used.
protected _errorIfPropertyHasNoValue(
property: string, // can contain dot-notation, i.e., 'property.subproperty'
propertyNameInError? = ''
) : void

// `The property "${propertyNameInError}" has no value.`
