1. Initial Commit - a boiler plate code and POC to realize the concept of context
sensitive help
2. Frontend code written in ReactJS
3. Backend code written in Java, Spring Boot Framework
4. Frontend Start:
pre-requisites : node, npm
npm run dev ==> to start the frontend vite server
5. Backend Start:
pre-requisites : java, mvn
mvn spring-boot:run ==> to start the backend server
6. Visit http://localhost:5173/ for basic demo of help, press F1 in textboxes
7. Visit http://localhost:5173/editor and enter "admin123" to add/modify texts.
Happy Coding !!!
Thank you,

/**
|
|
* Creates a throttled function that only invokes `func` at most once per
|
|
* every `wait` milliseconds. The throttled function comes with a `cancel`
|
|
* method to cancel delayed `func` invocations and a `flush` method to
|
|
* immediately invoke them. Provide `options` to indicate whether `func`
|
|
* should be invoked on the leading and/or trailing edge of the `wait`
|
|
* timeout. The `func` is invoked with the last arguments provided to the
|
|
* throttled function. Subsequent calls to the throttled function return the
|
|
* result of the last `func` invocation.
|
|
*
|
|
* **Note:** If `leading` and `trailing` options are `true`, `func` is
|
|
* invoked on the trailing edge of the timeout only if the throttled function
|
|
* is invoked more than once during the `wait` timeout.
|
|
*
|
|
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
|
|
* until to the next tick, similar to `setTimeout` with a timeout of `0`.
|
|
*
|
|
* See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
|
|
* for details over the differences between `_.throttle` and `_.debounce`.
