/**

|
* Returns true if the provided object is an Object (i.e. not a string literal)
|
||
|
|
* and implements the Iterator protocol.
|
||
|
|
*
|
||
|
|
* This may be used in place of [Array.isArray()][isArray] to determine if
|
||
|
|
* an object should be iterated-over e.g. Array, Map, Set, Int8Array,
|
||
|
|
* TypedArray, etc. but excludes string literals.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* ```ts
|
||
|
|
* isIterableObject([ 1, 2, 3 ]) // true
|
||
|
|
* isIterableObject(new Map()) // true
|
||
|
|
* isIterableObject('ABC') // false
|
||
|
|
* isIterableObject({ key: 'value' }) // false
|
||
|
|
* isIterableObject({ length: 1, 0: 'Alpha' }) // false
|
||
|
