With ImmutableJS.Record:

import memoize from 'immutablejs-record-memoize';
 
class ExampleRecord extends Record({}) {
    noArguments() {
        // ...
    },
 
    withArguments(a, b, c) {
        // ...
    }
}
 
memoize(ExampleRecord.prototype, ['noArguments', 'withArguments']);
 
// Use ExampleRecord as usual

For other object's prototypes:

import memoize from 'immutablejs-record-memoize';
 
function ExampleObject() {
    constructor() {

    },
 
    withArguments(a, b, c) {
        // ...
