The length
prototype property of the WebAssembly.Table
object returns the length of the table, i.e. the number of elements in the table.
table.length;
The following example creates a new WebAssembly Table instance with an initial size of 2 and a maximum size of 10.
var table = new WebAssembly.Table({ element: "anyfunc", initial: 2, maximum: 10 });
You can then grow the table by 1 with the following:
console.log(table.length); // "2" console.log(table.grow(1)); // "2" console.log(table.length); // "3"
