Lesson Words and Sentences

A box can hold words as well as numbers. Words go inside quote marks: var name = "Piccio";

The quote marks are the whole difference. They tell Visuco "this is text to keep", not code to run. Leave them off and it reads Sam as the name of a box, goes looking for a box called Sam, and stops with "Sam is not defined". So "Piccio" is a word, and Piccio with no quotes is a box name.

Whatever is between the quotes is kept exactly as typed. Capitals count — "Cat" and "cat" are two different pieces of text — and so do spaces, so "Well done" with two spaces is not the same as with one. When a challenge asks for particular words, copy them exactly.

The plus sign does a second job here. With numbers it adds: 5 + 3 makes 8. With words it joins them end to end: "5" + "3" makes 53. And if you mix the two, the number is turned into text and stuck on: "Level " + 5 makes Level 5.

Joining runs things straight together, so any gap has to be put there on purpose. That is what the lone space in first + " " + last is for — a piece of text one character long.

In this topic you will fill in words, add the quotes yourself, draw a box by name, and then join words and numbers into whole sentences.
