Answer №1

To define a variable and access its context, you can utilize the this keyword when declaring your function.

For instance:

let newFunction = "AwesomeDynamicFunction";

this[`${newFunction}`] = () => { 
  console.log("I'm an awesome dynamic function") 
}

Then, you can invoke it by using:

AwesomeDynamicFunction()

To achieve the desired result, you need to make some adjustments to your original code since it won't work as expected due to trying to input a string where a variable name is required.

Additionally, by using 'this' instead of 'window' or 'global', you can utilize the code snippet in both browser and node.js environments.

let variable = "something"

this[`constant${variable}`] = () => {
console.log("it works");
}
constantsomething()

To create a dynamic function using template literal, you have two options. One way is to utilize the window object like this:

let variable = "example"

    window[`dynamic${variable}`] = function () {
         console.log('creating dynamic function')
    }

Alternatively, you can use a separate object approach:

let variable = "example"

var obj = {
    [`dynamic${variable}`]: function () {
         console.log('creating dynamic function')
    }
}

obj.dynamicexample()

It's not possible like that, as a template literal is always resolved to a string and you cannot define a function "abc"() { ... }.

Nevertheless, you can attempt to place it in the global scope by using the name followed by bracket notation. For instance, if running in a browser:

let variable = "something"

window[`constant${variable}`] = function() {
  console.log("Hello!");
}

constantsomething();

In a Node.js project, the approach might look something like this:

let variable = "something"

global[`constant${variable}`] = function() {
  console.log("Hello!");
}

constantsomething();
