FutureScript Extension

npm install fus-ext

Copy node_modules/fus-ext/examples/manifest.fus file to your code's directory.

You code can be like this:

fus 0.1.0
import "./manifest" all

repeat[10, i ->
    console.log "This is \(i) time"
]

Here we used the "batch import" feature. Note that the export of manifest.fus should match the import of yours. If you want to use node instead of es, then you'll need to make corresponding changes in the version line of the two files.

If the iterator returns break then it means to jump out of the loop, similar to JS's break, but different in essence. Here break is an expression, and only capable of cancelling the remaining cycles, not capable of cancelling the remaining part of the function. If break then the repeat function returns break。This example is a loop, from 0 to 9, but it will jump out on 5:

repeat[10, i ->
    if i < 5
        console.log "This is \(i) time"
    else
        break
]

If no count is set, it means forever, equivalent to JS's while (true):

repeat --
    if abc()
        break
    else
        doSomething()

This corresponds to JS's for loop, from 1 to 10:

repeat{from: 1, to: 10, for: i ->
    console.log i
}

This corresponds to JS's for loop, from 10 to 1:

repeat{from: 10, to: 1, by: -1, for: i ->
    console.log i
}
