JavaScript Strings

A string is a piece of text.

Letters, words, sentences, and even empty text can be strings.

Think of beads on a string. Each character is one bead.

Quotes

You can use double quotes or single quotes.

Pick one style and stay steady in a file.

Joining with plus

Use + to glue strings together.

This is called concatenation.

Template strings

Backticks let you drop values inside with a dollar sign and curly braces.

This reads like filling blanks in a sentence.

Length

.length counts the characters.

Spaces count too.

Indexes

Each character has a number seat.

The first seat is 0.

Strings are not changed in place

When you build a new string, you get a new value.

The old text stays the same unless you save over the variable.

Tip: If a number looks stuck to text, check for strings. "2" + 2 becomes "22".
