usage
const { isBuffer } = require('@silen/is-buffer');
// or
import { isBuffer } from '@silen/is-buffer';
console.log(isBuffer(new Buffer(4)));
console.log(isBuffer(Buffer.alloc(4)));
console.log(isBuffer(undefined));
console.log(isBuffer(null));
console.log(isBuffer(''));
console.log(isBuffer(true));
console.log(isBuffer(0));
console.log(isBuffer(1));
console.log(isBuffer(1.0));
console.log(isBuffer('string'));
console.log(isBuffer({}));
console.log(isBuffer(function foo() {}));
console.log(isBuffer(Symbol()));
console.log(isBuffer(new Set));
console.log(isBuffer(new Map));
console.log(isBuffer(new WeakMap));
console.log(isBuffer(new WeakSet));
// or
console.log(window.Type.isBuffer(new WeakSet));This is a demo for testing the usage of isBuffer from @silen/is-buffer module. You can try the others and do likewise.
