    rangejs

    This is a micro-library which creates ranges using generators. Is similar to lodash/range but intead of returning an array it returns a generator which then you can iterate through. This approach can be quite usefull when there are memory allocation concerns/limitations.

    how to install

    npm install grangejs

    or

    yarn add grangejs

    how to use

    import { range } from 'grangejs';
    // const { range } = require('grangejs'); 
    
    // Using a for loop
    for(const num of range(10)) {
        console.log(num);
    }
    
    // outputs: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    
    // Using a while loop
    const gen = range(3);
    let result = gen.next();
    
    while(!result.done) {
        console.log(result.value);
        result = gen.next();
    }
    // outputs: 0, 1, 2
    
    // Getting values manually
    const gen = range(2);
    
    console.log(gen.next().value); // outputs: 0
    console.log(gen.next().value); // outputs: 1

    few other examples which you can use

    • range(-1, -4) -> -1, -2, -3
    • range(0, -10, -2) -> 0, -2, -4, -6, -8
    • range(0, -10, 2) -> 0, -2, -4, -6, -8
    • range(0, 10, 2) -> 0, 2, 4, 6, 8
    • range(0, 10, -2) -> 0, 2, 4, 6, 8
