The Int32Array() typed array constructor creates an array of twos-complement 32-bit signed integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).


new Int32Array()
new Int32Array(length)
new Int32Array(typedArray)
new Int32Array(object)

new Int32Array(buffer)
new Int32Array(buffer, byteOffset)
new Int32Array(buffer, byteOffset, length)

Note: Int32Array() can only be constructed with new. Attempting to call it without new throws a TypeError.
