Basic

import { make } from 'only-make'

const value = make(() => {
  // Make & return the value
})

Asynchronous

import { make } from 'only-make'

const value = await make(async () => {
  // Make & return the value
})

Golang Like Error Handling

Synchronously

import { make } from 'only-make'

const [value, error] = make(() => {
  // If success
  return [new_value, null]

  // If error
  return [null, new_error]
})

if (!error) {
  // Handle `error`
}

// Use `value` safely

Asynchronously

import { make } from 'only-make'

const [value, error] = await make(async () => {
  // If success
  return [new_value, null]

  // If error
  return [null, new_error]
})

if (!error) {
  // Handle `error`
}

// Use `value` safely

Access this

import { make } from 'only-make'

class MyClass {
  doSomething() {
    const value = make(() => {
      // Use `this`
    })
  }
}
