    local.get $a
    local.get $b
    i32.add

Load the wat synchronously:

const { requireWat } = require('require-wat');
const { add } = requireWat('./add.wat');

let result = add(1, 2);

console.log('1 + 2 is ' + result); // 1 + 2 is 3

or asynchronously:

const { requireWatAsync } = require('require-wat');

requireWatAsync('./add.wat')
    .then((wasmExports) => {
        const { add } = wasmExports;
        let result = add(1, 2);

        console.log('1 + 2 is ' + result); // 1 + 2 is 3
