Does json syntax allow duplicate keys in an object?
What this essentially means is that while having unique keys is recommended, it is not a must. We can have duplicate keys in a JSON object, and it would still be valid. The validity of duplicate keys in JSON is an exception and not a rule, so this becomes a problem when it comes to actual implementations.

What is bracket notation?
The alternate syntax for accessing object properties is known as bracket notation. In bracket notation, the object name is followed by a set of square brackets. Inside the square brackets, the property name is specified as a string. The previous example of dot notation has been rewritten below to use bracket notation. While the code may look different, it is functionally equivalent to the previous example.
Why is bracket notation more expressive than dot notation?
Bracket notation is more expressive than dot notation because it allows a variable to specify all or part of the property name. This is possible because the JavaScript interpreter automatically converts the expression within the square brackets to a string, and then retrieves the corresponding property. The following example shows how property names can be created on the fly using bracket notation. In the example, the property name foo is created by concatenating the contents of variable f, with the string "oo".
How to access nested objects?
Properties of nested objects can be accessed by chaining dot and/or bracket references together. For example, the following object contains a nested object named baz, which contains another object named foo, which has a property named bar that holds the value five.

What is the difference between diction and syntax?

Take the sentence "Beth slowly ran the race in wild, multicolored flip-flops." The sentence follows a subject-verb-object pattern ("Beth ran the race"). Adverbs and adjectives take their places in front of what they're modifying ("slowly ran"; "wild, multicolored flip-flops"). The object ("the race") follows the verb "ran", and the prepositional phrase ("in wild, multicolored flip-flops") starts with the preposition "in".
How has syntax changed over time?
Syntax has changed some over the development of English through the centuries. "The proverb Whoever loved that loved not at first sight? indicates that English negatives could once be placed after main verbs" (Aitchison, 2001).

Social dialects learned by people with common backgrounds—such as a social class, profession, age group, or ethnic group—also may influence the speakers' syntax. Think of the differences between teenagers' slang and more fluid word order and grammar vs. research scientists' technical vocabulary and manner of speaking to each other. Social dialects are also called "social varieties."
What are the different types of sentences?

Creating Objects
- Creating objects in JavaScript is easy. The language provides syntax known as object literal notationfor quickly creating objects. Object literals are denoted by curly braces.

Accessing Properties
- JavaScript provides two notations for accessing object properties. The first, and most common, is known as dot notation. Under dot notation, a property is accessed by giving the host object’s name, followed by a period (or dot), followed by the property name. The following example shows how dot notation is used to read from and write to a property. If object.foo initially held the value …
Functions as Methods
- When a function is used as an object property, it is called a method. Like properties, methods can also be specified in object literal notation. The following example shows how this is accomplished. Methods can also be invoked using dot and bracket notation. The following example invokes the sum()method from the previous example using both notations.
Adding Properties and Methods
- Object literal notation is useful for creating new objects, but it cannot add properties or methods to existing objects. Fortunately, adding new data to an object is as simple as creating an assignment statement. The following example creates an empty object. Two properties, foo and bar, and a method, baz, are then added using assignment statements. Note, that this example uses dot not…
