587d7b7c367417b2b2512b19 | Modify an Object Nested Within an Object | 1 |
Description
let nestedObject = {
id: 28802695164,
date: 'December 31, 2016',
data: {
totalUsers: 99,
online: 80,
onlineStatus: {
active: 67,
away: 13
}
}
};
nestedObject
has three unique keys: id
, whose value is a number, date
whose value is a string, and data
, whose value is an object which has yet another object nested within it. While structures can quickly become complex, we can still use the same notations to access the information we need.
Instructions
userActivity
, which includes another object nested within it. You can modify properties on this nested object in the same way you modified properties in the last challenge. Set the value of the online
key to 45
.
Tests
tests:
- text: '<code>userActivity</code> has <code>id</code>, <code>date</code> and <code>data</code> properties'
testString: 'assert("id" in userActivity && "date" in userActivity && "data" in userActivity, "<code>userActivity</code> has <code>id</code>, <code>date</code> and <code>data</code> properties");'
- text: <code>userActivity</code> has a <code>data</code> key set to an object with keys <code>totalUsers</code> and <code>online</code>
testString: 'assert("totalUsers" in userActivity.data && "online" in userActivity.data, "<code>userActivity</code> has a <code>data</code> key set to an object with keys <code>totalUsers</code> and <code>online</code>");'
- text: The <code>online</code> property nested in the <code>data</code> key of <code>userActivity</code> should be set to <code>45</code>
testString: 'assert(userActivity.data.online === 45, "The <code>online</code> property nested in the <code>data</code> key of <code>userActivity</code> should be set to <code>45</code>");'
- text: The <code>online</code> property is set using dot or bracket notation
testString: 'assert.strictEqual(code.search(/online: 45/), -1, "The <code>online</code> property is set using dot or bracket notation");'
