Answer: A function declaration is a distinct statement within the main body of code that identifies a function and its associated parameters. In contrast, a function expression is a function that is created within another syntax statement or expression.
Function declarations within a code block are visible throughout the entire block in Strict mode; however, this is not the case with function expressions. Function expressions are only visible within the scope of the code block in which they have been declared.
When the code is executed, a function expression is generated and can only be used from that point onwards. In contrast, a function declaration can be invoked prior to the definition of the function.
Answer: In the DOM renderer, an attribute is the original state, and a property is the current state.

For example, let exArray = new Array();
- Make use of an array constructor.
For example, var exArray = newArray(“hire,””Works,””developers”);
- Make use of an array literal.
For instance, var exArray = [“hire”,”Works”,”developers”];
- Create an array instance
