The read-only 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:

js
const table = new WebAssembly.Table({
  element: "anyfunc",
  initial: 2,
  maximum: 10,
});

Grow the table by 1 using WebAssembly.grow():

js
console.log(table.length); // 2
table.grow(1);
console.log(table.length); // 3
