Simple code in TS not working

[anant-k-singh]

I guess I am not using it correctly,

import memoizeOne from 'memoize-one';

const print = (list: Array<number>): void => list.forEach(num => {
    console.log(num);
});

const mem_print = memoizeOne(print);

let list = [1,2,3];

mem_print(list);
mem_print(list);

list = [...list, 4];

mem_print(list);

Compiled from TS 3.8 to JS with tsc index.js

"use strict";
var __spreadArrays = (this && this.__spreadArrays) || function () {
    for (var s = 0, i = 0, il = arguments.length; i < il; i++) s += arguments[i].length;
    for (var r = Array(s), k = 0, i = 0; i < il; i++)
        for (var a = arguments[i], j = 0, jl = a.length; j < jl; j++, k++)
            r[k] = a[j];
    return r;
};
exports.__esModule = true;
var memoize_one_1 = require("memoize-one");
var print = function (list) { return list.forEach(function (num) {
    console.log(num);
}); };
var mem_print = memoize_one_1["default"](print);
var list = [1, 2, 3];
mem_print(list);
mem_print(list);
list = __spreadArrays(list, [4]);
mem_print(list);

Output:

var mem_print = memoize_one_1["default"](print);
                                        ^

tsconfig

See big thread
#37

Shortly, enable esModuleInterop in your ts config.

Same issue with esModuleInterop: true.
My tsconfig

{
	"compilerOptions": {
		"target": "ES2018",
		"esModuleInterop": true,
		"allowSyntheticDefaultImports": true,
		"strict": true,
		"module": "esnext",
		"moduleResolution": "node",
	}
}
