Passing a string to `setTimeout` in browsers results in `eval` being used

setTimeoutEval.js

function logPIAfterDelay() {
  setTimeout(function () {
    console.log(Math.PI);
  }, 1000);
}

function logPIAfterDelayEval() {
  setTimeout("console.log(Math.PI)", 1000);
}

function logPIAfterDelayEvalStrict() {
  'use strict';
  setTimeout("console.log(Math.PI)", 1000);
}

/* 
  All three of these work in modern browsers (not in node though). Result in Node.js:
  
  timers.js:124
        first._onTimeout();
              ^
  TypeError: Property '_onTimeout' of object [object Object] is not a function
    at Timer.listOnTimeout (timers.js:124:15)
