Swazi Template Literals

SwaziLang supports template literals for easy string formatting and interpolation.
Template literals let you embed variables and expressions directly inside strings using backticks (`) and ${ ... } syntax.

---

Basic Syntax

data age = 25
data msg = `I am ${age} years old`
chapisha msg    // I am 25 years old

• Use backticks `...` to define a template literal.
• Wrap expressions or variables in ${ ... } to interpolate their values into the string.

---

Embedding Expressions

You can insert any valid expression inside ${ ... }:

data a = 5
data b = 10
data result = `Sum is ${a + b}`
chapisha result    // Sum is 15

data name = "Amina"
data score = 82
data status = score >= 50 ? "pass" : "fail"
data message = `${name} scored ${score} and is a ${status}`
chapisha message   // Amina scored 82 and is a pass

---

Multiline Strings

Template literals can span multiple lines:

data info = `Name: ${name}
Score: ${score}
Status: ${status}`
chapisha info

Output:

Name: Amina
Score: 82
Status: pass

---

Use Cases

• Variable interpolation: Easily insert values into text.
• Dynamic strings: Build messages with expressions and logic.
• Multiline formatting: Create readable, multi-line outputs.

Examples:

data user = "David"
data age = 30
chapisha `User ${user} is ${age} years old.`

data x = 8
chapisha `Double of ${x} is ${x * 2}`

---

Common Mistakes

• Forgetting backticks:
  Only backticks `...` allow interpolation. Single or double quotes do not:

  data wrong = "Value is ${x}"    // ❌ Does NOT interpolate

• Incorrect syntax inside ${ ... }:
  Only valid SwaziLang expressions are allowed.

---

Practice Challenge

Write a template literal that prints "Hello, [name]! You have [count] new messages."

Solution

data name = "Amina"
data count = 5
chapisha `Hello, ${name}! You have ${count} new messages.`

---

Summary:

• Use backticks for template literals.
• Interpolate variables and expressions with ${ ... }.
• Template literals make string formatting in SwaziLang simple and readable!
