How to Do String Interpolation in JavaScript?

This article explains interpolation and shows you how to apply it to the strings to increase their tensile strength. Additionally, you will comprehend how to operate string interpolation to improve programming code. Lastly, you will see several code examples to demonstrate the use of JavaScript strings for interpolation to get the facts.

Introduction of JavaScript Interpolation

A great advantage of programming languages is string interpolation, which enables the injection of variables, function calls, and mathematical operators directly into a string. JavaScript did not have string interpolation prior to ES6. A new feature of ES6 is string interpolation, which allows you to create multi-line strings without using an escape character. Apostrophes and quotations are simple to utilize, which helps to make our strings and our code easier to read. Some justifications for choosing string interpolation over string concatenation.

String Interpolation in JavaScript

The template literal in JavaScript allows you to append values to a string. This is a dollar sign, and two curly brackets come next. The expression that you wish to embed the value of in the string should be enclosed in curly brackets.

The values are embedded into a string using template literals instead of concatenation. Instead of using quotation marks to encapsulate your string, use backticks ("") to declare a template literal.

Syntax

The string where interpolation is enclosed in backticks: expression`

In JavaScript, placeholders allow for the dynamic insertion of inputs into string segments through string interpolation. The conventional method of appending variables to strings does not support this possibility. Look at the syntax below:

The below expression is declared the template literal.

The phrase "5 + 6" is evaluated as the result of this expression. This is a result of our expression being typed before the complete stop.

Examples

The following examples show the javascript string interpolation.

Example 1:

The following example shows the basic javascript string interpolation. We can use the expression substitution in the interpolation. The addition and mathematical operation can work with the string interpolation function.

Output

The output shows the javascript interpolation.

Example 2:

The following example shows the basic javascript string interpolation. We can use the string substitution in the interpolation. The string and arithmetic operators can be used in the interpolation function in the javascript.

Output

The output shows the javascript interpolation.

Example 3:

The following example shows the basic javascript string interpolation. We can create an array and use interpolation in the string to display value.

Output

The output shows the javascript interpolation.

Example 4:

The following example shows the basic javascript string interpolation. We can create a javascript function and use string interpolation to operate the functionality.

Output

The output shows the javascript interpolation.

Example 5:

The following example shows the basic javascript string interpolation. If the condition is applied to the function with the logical and mathematical operation, then the string shows output.

Output

The output shows the javascript interpolation.

Conclusion

String interpolation helps to operate functionality and operators directly. It can handle data, output data, and operational data simultaneously. It helps to develop applications quickly and easily.
