List

an ordered collection of elements

Element

an individual value in a list that is assigned a unique index.

For loop

1. A particular kind of looping construct provided in many languages. Typically, this loop defines a counting variable that is checked and incremented on each iteration in order to loop a specific number of times.

Loops (iteration statement)

1. change the sequential flow of control by repeating a set of statements zero or more times, until a stopping condition is met

Index

1.  a common method for referencing the elements in a list or string using numbers

Length of list

1. how many elements it contains. Lists can grow or shrink as elements are added or removed.

Iteration

1.  a repetitive portion of an algorithm which repeats a specified number of times or until a given condition is met

Infinite loop

1. occurs when the ending condition will never evaluate to true

Traversal

1. the process of accessing each item in a list one at a time

Append

adds an element to the end of a list

Insert

Inserts an element into a list at the index given

Remove

Removes the element in a given list at the given index

Data abstraction

1. manages complexity in programs by giving a collection of data a name without referencing the specific details of the representation

Logic error

1.  a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.

Run-time error

1. a mistake in the program that occurs during the execution of a program. Programming languages define their own runtime errors.

Syntax error

1. a mistake in the program where the rules of the programming language are not followed

Ways to find and correct errors

1.  test cases, hand tracing, visualizations, watchers, adding extra output statements (console.logs)

Simulation

1. abstractions of more complex objects or phenomena for a specific purpose.Simulations are most useful when real-world events are impractical for experiments (e.g., too big, too small, too fast, too slow, too expensive, or too dangerous).

Substring

part of an existing string
