🎯چه وقت باید از پوینتر استفاده کنیم؟
🔰 @gopher_academy
👇👇👇👇
🔺1. تابعی که یکی از پارامترهای خود را تغییر می‌دهد
🔹وقتی تابعی را فراخوانی می‌کنیم که یک پوینتر را به عنوان پارامتر می‌گیرد، انتظار داریم که متغیر ما تغییر داده شود. اگر شما متغیر را در تابع خود تغییر نمی‌دهید، پس احتمالا نباید از پوینتر استفاده کنید.

🔻2. عملکرد بهتر
🔹اگر رشته‌ای داشته باشید که شامل یک رمان کامل در حافظه باشد، کپی کردن این متغیر هر بار که به یک تابع جدید ارسال می‌شود، کاری بسیار گران است. ممکن است ارزشمند باشد که به جای این کار یک پوینتر را ارسال کنید، که باعث صرفه‌جویی در پردازنده و حافظه می‌شود. با این حال انجام این کار به قمیت خوانا بودن است، بنابراین فقط در صورت لزوم این بهینه‌سازی را انجام دهید.

🔻3. به گزینه Nil نیاز دارید
🔹گاهی اوقات یک تابع باید بداند که مقدار یک چیزی چیست، همچنین باید وجود یا عدم وجود آن را بداند. معمولا هنگام خواندن JSON از این استفاده می‌کنیم تا بدانیم فیلدی وجود دارد یا خیر.
