how to use the template function from the lodash library in typescript

To use the template function from the Lodash library in TypeScript, we need to install the Lodash library and import the template function from it. Here are the steps to do that:

1. Install the Lodash library using npm:

index.ts
npm install lodash
19 chars
2 lines

2. Import the template function in your TypeScript file:

index.ts
import { template } from 'lodash';
35 chars
2 lines

3. Now you can use the template function to compile a template string:

index.ts
const compiled = template('Hello <%= user %>!');
const result = compiled({ 'user': 'John' });
console.log(result); // Output: Hello John!
138 chars
4 lines

In the above code, we first create a template string using the Lodash syntax. The <%= user %> is a variable placeholder that will be replaced with the value of the user key in the data object that we pass to the compiled function. We then pass a data object to the compiled function, which returns the compiled template string. Finally, we print the compiled string to the console.

Note that the template function returns a function that we can use to compile a template string with a different set of data. We can also pass additional options to the template function, such as the escape and evaluate delimiters. For more information, see the Lodash documentation on the template function.
