What is String Interpolation?
Embedding variables or expressions directly inside a string, so their values appear in the final text.
Why It Matters
String interpolation makes code more readable than concatenating strings with + signs.
Real-World Example
Writing `Hello, ${name}!` in JavaScript instead of 'Hello, ' + name + '!'.
“Understanding terms like String Interpolation matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
