相关任务： 关联数组/创建

Instructions

Tests

tests:
  - text: <code>arrToObj</code>是一个功能。
    testString: assert(typeof arrToObj === 'function');
  - text: '<code>arrToObj([1, 2, 3, 4, 5], ["a", "b", "c", "d", "e"])</code>应返回<code>{ 1: "a", 2: "b", 3: "c", 4: "d", 5: "e" }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[0]), res[0]);
  - text: '<code>arrToObj([1, 2, 3, 4, 5], ["a", "b", "c", "d"])</code>应返回<code>{ 1: "a", 2: "b", 3: "c", 4: "d", 5: undefined }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[1]), res[1]);
  - text: '<code>arrToObj([1, 2, 3], ["a", "b", "c", "d", "e"])</code>应返回<code>{ 1: "a", 2: "b", 3: "c" }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[2]), res[2]);
  - text: '<code>arrToObj(["a", "b", "c", "d", "e"], [1, 2, 3, 4, 5])</code>应返回<code>{ "a": 1, "b": 2, "c": 3 , "d": 4, "e": 5 }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[3]), res[3]);
  - text: '<code>arrToObj(["a", "b", "c", "d", "e"], [1, 2, 3, 4])</code>应返回<code>{ "a": 1, "b": 2, "c": 3 , "d": 4, "e": undefined }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[4]), res[4]);
  - text: '<code>arrToObj(["a", "b", "c"], [1, 2, 3, 4, 5])</code>应返回<code>{ "a": 1, "b": 2, "c": 3 }</code>'
    testString: assert.deepEqual(arrToObj(...testCases[5]), res[5]);

Challenge Seed

function arrToObj (keys, vals) {
  // Good luck!
  return true;
}

After Test

console.info('after the test');
