WebAssembly.Table.prototype.length

The length prototype property of the WebAssembly.Table object returns the length of the table, i.e. the number of elements in the table.

Examples

Using 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"
