我的代码高尔夫同事想出了这个（ES6），包容的：

(s,f)=>[...Array(f-s+1)].map((e,i)=>i+s)

非包容性：

(s,f)=>[...Array(f-s)].map((e,i)=>i+s)

带增量/步长

smallest and one-liner

[...Array(N)].map((_, i) => from + i * step);

示例和其他备选方案

[...Array(10)].map((_, i) => 4 + i * 2);
//=> [4, 6, 8, 10, 12, 14, 16, 18, 20, 22]

Array.from(Array(10)).map((_, i) => 4 + i * 2);
//=> [4, 6, 8, 10, 12, 14, 16, 18, 20, 22]

Array.from(Array(10).keys()).map(i => 4 + i * 2);
//=> [4, 6, 8, 10, 12, 14, 16, 18, 20, 22]

[...Array(10).keys()].map(i => 4 + i * -2);
//=> [4, 2, 0, -2, -4, -6, -8, -10, -12, -14]

Array(10).fill(0).map((_, i) => 4 + i * 2);
//=> [4, 6, 8, 10, 12, 14, 16, 18, 20, 22]

Array(10).fill().map((_, i) => 4 + i * -2);
//=> [4, 2, 0, -2, -4, -6, -8, -10, -12, -14]

Range Function

const range = (from, to, step) =>
  [...Array(Math.floor((to - from) / step) + 1)].map((_, i) => from + i * step);

range(0, 9, 2);
//=> [0, 2, 4, 6, 8]

// can also assign range function as static method in Array class (but not recommended )
Array.range = (from, to, step) =>
  [...Array(Math.floor((to - from) / step) + 1)].map((_, i) => from + i * step);

Array.range(2, 10, 2);
//=> [2, 4, 6, 8, 10]

Array.range(0, 10, 1);
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Array.range(2, 10, -1);
//=> []

Array.range(3, 0, -1);
//=> [3, 2, 1, 0]

As Iterators

class Range {
  constructor(total = 0, step = 1, from = 0) {
    this[Symbol.iterator] = function* () {
      for (let i = 0; i < total; yield from + i++ * step) {}
    };
  }
}

[...new Range(5)]; // Five Elements
//=> [0, 1, 2, 3, 4]
[...new Range(5, 2)]; // Five Elements With Step 2
//=> [0, 2, 4, 6, 8]
[...new Range(5, -2, 10)]; // Five Elements With Step -2 From 10
//=>[10, 8, 6, 4, 2]
[...new Range(5, -2, -10)]; // Five Elements With Step -2 From -10
//=> [-10, -12, -14, -16, -18]

// Also works with for..of loop
for (i of new Range(5, -2, 10)) console.log(i);
// 10 8 6 4 2

As Generators Only

const Range = function* (total = 0, step = 1, from = 0) {
  for (let i = 0; i < total; yield from + i++ * step) {}
};

Array.from(Range(5, -2, -10));
//=> [-10, -12, -14, -16, -18]

[...Range(5, -2, -10)]; // Five Elements With Step -2 From -10
//=> [-10, -12, -14, -16, -18]

// Also works with for..of loop
for (i of Range(5, -2, 10)) console.log(i);
// 10 8 6 4 2

// Lazy loaded way
const number0toInf = Range(Infinity);
number0toInf.next().value;
//=> 0
number0toInf.next().value;
//=> 1
// ...

带步长/增量的从到

using iterators

class Range2 {
  constructor(to = 0, step = 1, from = 0) {
    this[Symbol.iterator] = function* () {
      let i = 0,
        length = Math.floor((to - from) / step) + 1;
      while (i < length) yield from + i++ * step;
    };
  }
}
[...new Range2(5)]; // First 5 Whole Numbers
//=> [0, 1, 2, 3, 4, 5]

[...new Range2(5, 2)]; // From 0 to 5 with step 2
//=> [0, 2, 4]

[...new Range2(5, -2, 10)]; // From 10 to 5 with step -2
//=> [10, 8, 6]

using Generators

const Range2 = function* (to = 0, step = 1, from = 0) {
  let i = 0,
    length = Math.floor((to - from) / step) + 1;
  while (i < length) yield from + i++ * step;
};

[...Range2(5, -2, 10)]; // From 10 to 5 with step -2
//=> [10, 8, 6]

let even4to10 = Range2(10, 2, 4);
even4to10.next().value;
//=> 4
even4to10.next().value;
//=> 6
even4to10.next().value;
//=> 8
even4to10.next().value;
//=> 10
even4to10.next().value;
//=> undefined

对于字体

class _Array<T> extends Array<T> {
  static range(from: number, to: number, step: number): number[] {
    return Array.from(Array(Math.floor((to - from) / step) + 1)).map(
      (v, k) => from + k * step
    );
  }
}
_Array.range(0, 9, 1);

用一行代码生成字符列表

constcharList=（a，z，d=1）=>（a=a.charCodeAt（），z=z.charCodeAt（），[…数组（Math.floor（（z-a）/d）+1）].map（（_，i）=>String.fromCharCode（a+i*d）））；console.log（“从A到G”，charList（'A'，'G'））；console.log（“从A到Z，步长/增量为2”，charList（'A'，'Z'，2））；console.log（“从Z到P的反向顺序”，charList（'Z'，'P'，-1））；console.log（“从0到5”，charList（“0”，“5”，1））；console.log（“从9到5”，charList（'9'，'5'，-1））；console.log（“从0到8，步骤2”，charList（'0'，'8'，2））；console.log（“从α到ω”，charList（“α”，“ω”））；console.log（“印地语字符来自क 到ह“，charList（'क', 'ह'));console.log（“从А到Е的俄语字符”，charList（“А”，“Е”））；

For TypeScript

const charList = (p: string, q: string, d = 1) => {
  const a = p.charCodeAt(0),
    z = q.charCodeAt(0);
  return [...Array(Math.floor((z - a) / d) + 1)].map((_, i) =>
    String.fromCharCode(a + i * d)
  );
};

您还可以执行以下操作：

const range = Array.from(Array(size)).map((el, idx) => idx+1).slice(begin, end);

这里是一个范围函数的定义，它的行为与Python的范围类型完全相同，只是这个函数不是懒惰的。把它变成发电机应该很容易。

范围构造函数的参数必须是数字。如果省略step参数，则默认为1。如果省略了start参数，则默认为0。如果步骤为零，则会引发错误。

range = (start, stop, step=1) => {
    if(step === 0) throw new Error("range() arg 3 must not be zero");

    const noStart = stop == null;
    stop = noStart ? start : stop;
    start = noStart ? 0 : start;
    const length = Math.ceil(((stop - start) / step));

    return Array.from({length}, (_, i) => (i * step) + start);
}

console.log(range(-10, 10, 2));
//output [Array] [-10,-8,-6,-4,-2,0,2,4,6,8]
console.log(range(10));
// [Array] [0,1,2,3,4,5,6,7,8,9]
console.log(3, 12);
// [Array] [3,4,5,6,7,8,9,10,11]

Op要求范围，例如范围（3，10），因此可以

[...[...Array(10-3).keys()].map(i => i+3)]

回报

[3, 4, 5, 6, 7, 8, 9]

一个可以在任一方向工作的衬垫：

const range = (a,b)=>Array(Math.abs(a-b)+1).fill(a).map((v,i)=>v+i*(a>b?-1:1));

请参阅实际操作：

常量范围=（a，b）=>数组（数学.abs（a-b）+1）.fill（a）.map（（v，i）=>v+i*（a>b？-1:1））；console.log（范围（1,4））；console.log（范围（4,1））；
