Parameters

index: number

Index at which to start deleting elements

length?: number

The number of elements to remove. Defaults to 1.

Returns

void

forEach()

forEach(f): void

Executes a provided function once on overy element of this YArray.

Parameters

f

A function to execute on every element of this YArray.

insert()

insert(index, content): void

Inserts new content at an index.

Important: This function expects an array of content. Not just a content object. The reason for this "weirdness" is that inserting several elements is very efficient when it is done as a single operation.

Parameters

index: number

The index to insert content at.

content: T[]

The array of content

Returns

void

Example

ts
// Insert character 'a' at position 0
 yarray.insert(0, ['a'])
 // Insert numbers 1, 2 at position 1
 yarray.insert(1, [1, 2])
