It is difficult because one small word changes value based on <strong>how a function is called</strong>.</p> <p>That makes <code>this</code> look unpredictable when the real problem is usually that we are looking in the wrong place.</p> <p>For an ordinary function, do not start with where the function was written. Start with the call-site.</p> <blockquote> <p><strong>The call usually decides <code>this</code>.</strong></p> </blockquote> <p>That one rule explains most of the behavior you will meet in day-to-day JavaScript.</p>
