This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The grow() protoype property of the Memory object increases the size of the memory instance by a specified number of WebAssembly pages.
memory.grow(number);
Void.
The following example creates a new WebAssembly Memory instance with an initial size of 10 pages (640KB), and a maximum size of 100 pages (6.4MB).
var memory = new WebAssembly.Memory({initial:10, maximum:100}); We can then grow the instance by one page like so:
memory.grow(1);
