Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including @simplyhexagonal/elean. Try it out:
const elean = require('@simplyhexagonal/elean');
// ----------------------------------------------------------------------------
console.log('> FALSE:');
let ENV_VAR; // undefined
console.log(elean(ENV_VAR));
ENV_VAR = '';
console.log(elean(ENV_VAR));
ENV_VAR = 'undefined';
console.log(elean(ENV_VAR));
ENV_VAR = null;
console.log(elean(ENV_VAR));
ENV_VAR = 'null';
console.log(elean(ENV_VAR));
ENV_VAR = 'NULL';
console.log(elean(ENV_VAR));
ENV_VAR = 0;
console.log(elean(ENV_VAR));
ENV_VAR = '0';
console.log(elean(ENV_VAR));
ENV_VAR = false;
console.log(elean(ENV_VAR));
ENV_VAR = 'false';
console.log(elean(ENV_VAR));
ENV_VAR = 'FALSE';
console.log(elean(ENV_VAR));
// -----------------------------------------------------------------------------
console.log('> TRUE:');
ENV_VAR = 'xyz';
console.log(elean(ENV_VAR));
ENV_VAR = 1;
console.log(elean(ENV_VAR));
ENV_VAR = '1';
console.log(elean(ENV_VAR));
ENV_VAR = true;
console.log(elean(ENV_VAR));
ENV_VAR = 'true';
console.log(elean(ENV_VAR));
ENV_VAR = 'TRUE';
console.log(elean(ENV_VAR));
