EP15 — The 'this' Keyword — Part 1
<p>The same function can give a completely different value of 'this'</p><p>depending on nothing more than how you called it. Not where you</p><p>wrote it — how you called it.</p><p><br></p><p>In this episode, Alex Vega explains the four binding rules that</p><p>determine 'this' — default, implicit, explicit, and new — and the</p><p>strict priority order between them, through the analogy of the word</p><p>"here." Plus the most common 'this' bug in all of JavaScript:</p><p>losing it in a callback.</p><p><br></p><p>Oh, That's Why. — JavaScript, finally making sense.</p><p><br></p><p>You can find the Medium article <a href="https://medium.com/@gize.bonilla/1e2fff3363f9">here</a>. </p><p><br></p><p>#JavaScript, #Web Development, #Programming, #Software Engineering,</p><p>#Learning to Code.</p>

EP14 — Prototypes & The Prototype Chain
<p>Every array you create comes with .map(), .filter(), .reduce() —</p><p>methods you never wrote. Where do they come from?</p><p><br></p><p>In this episode, Alex Vega explains the prototype chain — the hidden</p><p>mechanism behind property lookup in JavaScript — through the linked</p><p>filing cabinet analogy. By the end, you understand why every array</p><p>has those methods, how Object.create works, and why instanceof</p><p>behaves the way it does.</p><p><br></p><p>You can find the Medium article <a href="https://medium.com/@gize.bonilla/0c6810da15a5">here</a>.</p><p><br></p><p>Oh, That's Why. — JavaScript, finally making sense.</p><p><br></p><p>#JavaScript, #Web Development, #Programming, #Software Engineering,</p><p>#Learning to Code</p>

EP13 — Objects — How They Really Work
<p>An object is just key-value pairs. So why does a property sometimes</p><p>refuse to update with no error? Why is a key missing from your loop</p><p>even though it's right there in the object?</p><p><br></p><p>In this episode, Alex Vega explains property descriptors — writable,</p><p>enumerable, configurable — through a museum exhibit analogy, and covers</p><p>Object.freeze, Object.seal, and the modern shorthand syntax that can</p><p>quietly interact with all of it.</p><p><br></p><p>Oh, That's Why. — JavaScript, finally making sense.</p><p><br></p><p>You can find the Medium article <a href="https://medium.com/@gize.bonilla/576e36a901f0">here</a>.</p><p><br></p><p>#JavaScript, #Web Development, #Programming, #Software Engineering,</p><p>#Learning to Code</p>
