    The collection of bindings and their values that exist at a given time is called
    the environment
  4. What is a function?
    function is a piece of program wrapped in a value. Such values can be applied
    in order to run the wrapped program.
  5. Give an example of a function.
  6. What is a side effect?
    Showing a dialog box or writing text to the screen is a side effect.
  7. Give an example of a function that produces a side effect and another function that produces a value.
  8. What is control flow?
    When your program contains more than one statement, the statements are
    executed as if they are a story, from top to bottom
  9. What is conditional execution?
    where the program takes the proper branch based on the
    situation at hand.

  1. A fragment of code that produces a value is called an expression.
    Every value that is written literally (such as 22 or “psychoanalysis”) is an expression. An expression between parentheses is also an expression, as is a binary operator applied to two expressions or a unary operator applied to one.

  2. To catch and hold values, JavaScript provides a thing called a binding, or variable:

    let caught = 5 * 5;

    That’s a second kind of statement. The special word (keyword) let indicates that this sentence is going to define a binding. It is followed by the name of the binding and, if we want to immediately give it a value, by an operator(=) and an expression. The previous statement creates a binding called caught and uses it to grab hold of the number that is produced by multiplying 5 by 5. After a binding has been defined, its name can be used as an expression. The value of such an expression is the value the binding currently holds.
    When a binding points at a value, that does not mean it is tied to that value forever. The = operator can be used at any time on existing bindings to disconnect them from their current value and have them point to a new one. The words var(variable) and const(constant) can also be used to create bindings, in a way similar to let.

  3. The collection of bindings and their values that exist at a given time is called the environment.
    When a program starts up, this environment is not empty. It always contains bindings that are part of the language standard, and most of the time, it also has bindings that provide ways to interact with the surrounding system.

  4. A function is a piece of program wrapped in a value.

  5. In a browser environment, the binding prompt holds a function that shows a little dialog box asking for user input. It is used like this:
    prompt(“Enter passcode”);

  6. A JavaScript statement is an aggregation of expressions.
    A program is a list of statements. A statement stands on its own, and it could display something on the screen or it could change the state of the internal state of the machine in a way that will affect the statements that come after it. These changes are called side effects.

  7. side effect : propmt(“Enter your name”)
    value : var b = 4

  8. When your program contains more than one statement, the statements are executed as if they are a story, from top to bottom. Control flow is the order in which statements are executed.

  9. In addition to control flow’s “straight line” structure, we might need to create a “branching road” where the program takes the proper branch based on the situation at hand. This is called conditional execution.

  10. Contitional execution is created with the if keyword. The if keyword executes or skips a statement depending on the value of a Boolean expression. The deciding expression is written after the keyword, between parentheses, followed by the statement to execute.
    You can use the else keyword, together with if, to create two separate, alternative execution paths.
    If you have more than two paths to choose from, you can “chain” multiple if,else pairs together.
    (if, else, else if)

  6. What is a side effect?
    A side effect is produced by a function changing something. This could include displaying something on the screen or changing the internal state of the machine in order to effect the statements that come after it.
  7. Give an example of a function that produces a side effect and another function that produces a value.
    A function that produces a side effect is the alert() function.
    A function that produces a value is Math.max

Expression is a piece of code that produces some kind of value.

Binding or variable holds values.

Environment is a collection of bindings and their values at given moment.

Function is a piece of program that is wrapped in a value. A lot of the values provided in the default environment have the type function.

Example of functions: prompt, console.log.

A side effect is showing a dialog box or writing text to the screen.

Function that produces a side effect is : Math.max
Function that produces a value: Math.min

When program contains more than one statement, the statements are executed from top to the bottom. This is control flow.

Conditional execution is when we want to create a branching road, where the program takes the proper branch based on situation at hand.

The keyword “if” invokes a conditional execution.

  1. An expression is a part of coding that produces a value.
  2. A binding is a way for javascript to hold or remember a value for later use.
  3. The environment is where the binding and values are kept in memory.
  4. A function is a piece of expressive programming for a value/s.
  5. An example of a function is prompt.
  6. A side effect is where a program has something happen after deployment that noticeably changes something. Versus the program being erased right after it is used, with no changes other than maybe a value being produced.
  7. A function that produces a side effect is prompt. A function that produces a value is MATH.max.
  8. Control flow is where the programming being executed goes from first to last in the coding. When options become available for different paths, in the programming, the flow of programming can go one or more ways depending on the input of the user.
  9. Conditional execution is like a choose-your-own adventure book. Where the user chooses which way the program will take them according to what choices were made.
    10.The keyword “if” is used. And when another path is needed “else” is used afterwards.

  2. What is a binding?
    Binding allows Javascript to catch and hold values. Example, let caught=5*5.
    Imagine bindings like tentacles, rather than boxes. They don’t contain values, they grasp them. Variables and Contants can be used to create Bindings.

Bindings can include a ‘$’ or an ‘_’ (underscore)
let is the keyword for bindings
