SDK is apparently our bestie when we make double-checks on our page, an irreplaceable tool to access front-ended surface and its source codes. Abbreviated from the term “Software Development Kit”, literally, we could easily notice this kit-set is base on the instant condition of a page through the codes and require every unexpected mistake we probably have. Today, I’d like to share about how does SDK look alike, what it works its functions and how should we use it as a junior developer in 5 examples.

Every window page has its own mini database and we’d like to call it a local storage. One api is being input a set of key and value, an informative item could be sent back into local storage in a need of temporary saving. Image a local storage is as a repository which could keep some limited during a reload or some inconvenient damages, especially when we’re having a online shopping and just ordered an item into our chart, not lasts for good but long enough to keep our details not in valid.
