Values, types, and the console

入门~20 分钟0/4 步骤

Your first Smart Ledger snapshot

JavaScript programs start with values. A business name is text, revenue is a number, and VAT registration is a yes/no fact. In this module you will store each value, inspect its type, and render a business snapshot on the page.

The browser console is a diagnostic tool, not a place to guess. Use it to see what the program actually knows.

操作说明

1

Create a constant named businessName and assign it a string.

提示: Use: const businessName = '...';

2

Create monthlyRevenue as a number and vatRegistered as a boolean.

3

Log the type of at least one value with typeof.

4

Write the snapshot into the element with id output.
