Comparing jq VS js String Interpolation

The aim of this page is to explain string interpolation based on the particular example of using JQ tool and JavaScript.

String interpolation allows inserting variables and expressions into strings.
JQ tool uses \(.variable) for string interpolation.
JavaScript uses ${variable} for string interpolation.
Example of JQ tool:

echo '{ "id": 12345, "subject": "Subject line here" }' | jq -r '"\(.id) \(.subject)"'

In JQ tool, variables are enclosed in parentheses and prefixed with a backslash.
Example of JavaScript:

const id = 12345;
const subject = "Subject line here";
const result = `${id} ${subject}`;
console.log(result); // Output: 12345 Subject line here

In JavaScript, template literals are enclosed in backticks.
Variables are embedded using `${}`.
Template literals allow embedding expressions and multiline strings.
String interpolation is useful for generating dynamic strings.
