JS ⟩ objects ⟩ built-in ⟩ Generator ⟩ generator function ⟩ compostion ⟩ *sequence()

yield the values of iterables sequentially.

yield* operator - can only be used within generator functions❗️

replit：sequence(...iterables)

// ⭐ sequence()
//  yield the values of iterables sequentially
function* sequence(...iterables) {
    for (const iterable of iterables) {
        yield* iterable;
    }
}

// export
module.exports = sequence;

💈範例：

require： Iterator, *integers()

// ⭐ import
const Iterator = require('./Iterator.js');    // extend iterators
const integers = require('./integers.js');    // integers()
const sequence = require('./sequence.js');    // sequence()
// --------------------------------------------------------------

sequence(                 // iterables:
    integers().take(5),   //   • 0 ,  1 , 2, 3, 4
    "ab",                 //   • 'a', 'b'
    [0]                   //   • 0
).toArray()
// [ 0, 1, 2, 3, 4, 'a', 'b', 0]
