Really really wanted my first
Really really wanted my first YouTube video this year to be a Tutorial! It’s a symbol that this year is going to be filled with a LOT of tutorials - starting with finishing 𝐃𝐞𝐬𝐢𝐠𝐧 𝐏𝐚𝐭𝐭𝐞𝐫𝐧 𝐒𝐞𝐫𝐢𝐞𝐬.
Today’s video is on 𝐒𝐢𝐧𝐠𝐥𝐞𝐭𝐨𝐧 𝐃𝐞𝐬𝐢𝐠𝐧 𝐏𝐚𝐭𝐭𝐞𝐫𝐧. I know most people think they know this design pattern as it’s a basic and common one, but there are details to it that we end up missing. Making the code thread safe and efficient is important when it comes to implementing the code.
So, obviously. I have covered everything with code in detail. Link is in comments. Please keep sharing your feedback.
If you guys really want educators to be motivated and create a lot of tutorials, please do support us - just a like, share or subscribe can mean a lot to us. Trust me - a LOT of effort goes behind these videos!
