Array
An indexed collection that stores same-type values in sequence
Core Idea
An array stores values in order and lets you access them by index. That makes it the natural starting point for looping, aggregating, searching, and rendering repeated data.
The syntax changes across languages, but the shared idea does not: values live in a sequence, and your code walks that sequence. In C arrays connect directly to memory layout and pointers, while in JavaScript and Python they often anchor data transformation and UI rendering. Many languages also connect strings closely to arrays of characters.
Why It Matters Here
Mathbong uses arrays not just as syntax but as the first reusable "repeatable structure." That makes them an important bridge to topics such as coefficient arrays, matrices, list rendering, and other collection patterns.
