please follow above spec. the behavior might not be exactly the same as lodash.debounce()

because window.setTimeout and window.clearTimeout are not accurate in browser environment, they are replaced to other implementation when judging your code. They still have the same interface, and internally keep track of the timing for testing purpose.
