exec-string

Utility to execute a string as a function.

Installation

npm install exec-string

Usage

const execString = require('exec-string');

// Example use-cases

const result = execString('420 + 1337') // Returns 1757

const num1 = 42;
const num2 = 43;
const comparator = '<';

const comparison = execString(`${num1} ${comparator} ${num2}`); // Returns true

Can also be used with React or other libraries.

For instance, you can use it to pass a mathematical expression as props to a component. exec-string can return the value of the expression and display it in the UI.
