Object Discussion Questions

There is some coding in this discussion. Feel free to write them in a REPL or in the comments below.

0. How is an object different from an array?
1. How does const work with objects?
2. Explain the difference between bracket syntax and dot syntax. Give an example of something that works with bracket syntax but not dot syntax. Give an example of something that works with dot syntax but not bracket syntax.
3. What are computed properties? Write an example code.
4. What is the difference between Object.keys and Object.entries? Write example code using both of them.
5. How do we get only the values of an object?

0. Object is a data type, array is an object as well. Object has properties like boolean,strings etc.
1. we use const with the object if we don't want to change the value which is certain.
2. Sometimes it is impossible to access those properties with dot notation. wildKeys.'string' ;

0. Objects can store pairs (keys and values). Arrays only store values.
1. Const creates a binding so we can't use the same name with another object.
2. Dot notation is easier to read and write. Cheat: Square bracket notation allows access to properties containing special characters and selection of properties using variables.

4.The Object.keys() function returns an array of the object's own properties. Object.entries() function returns an array of entries.
5.Object.values
