Lets say I have a Javascript function that adds two numbers as follows
function addNumbers(a, b){ return a+b; } Then I want to output to the console the result of calling the function with two numbers. When using string concatenation I can do the following:
console.log('The sum of two numbers is' + addNumbers(a, b)); However, my question is how do I call the function if I want to use string interpolation? Something like:
console.log(`the sum of two numbers is addNumbers(a, b)`); As always, the expression you want to output the result of evaluating goes between ${ and }.
function addNumbers(a, b) { return a + b; } const a = 4; const b = 6; console.log(`the sum of two numbers is ${addNumbers(a, b)}`);
All you have to is wrap the expression with ${}
console.log(`the sum of two numbers is ${addNumbers(a, b)}`); Template literals are enclosed by the back-tick (``) (grave accent) character instead of double or single quotes. Template literals can contain placeholders. These are indicated by the dollar sign and curly braces (${expression})
You can execute any expression inside of template literals (``) with a inside a $ and curly braces (${}).
Your example would look like this:
console.log(`the sum of two numbers is ${addNumbers(a, b)}`); See mdn docs for more information.
