示例

ms formats millisecond values only up to days without week or year units, keeps 'ms' in long mode for sub-second values, and exhibits asymmetric negative rounding.

常见的想当然

Formatting millisecond values scales symmetrically to week or year units and expands sub-second values to 'milliseconds' when long formatting is requested.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert.strictEqual(ms(604800000), '7d');
• assert.strictEqual(ms(31557600000), '365d');
• assert.strictEqual(ms(604800000, { long: true }), '7 days');
• assert.strictEqual(ms(31557600000, { long: true }), '365 days');
• assert.strictEqual(ms(500, { long: true }), '500 ms');
• assert.strictEqual(ms(1500), '2s');
• assert.strictEqual(ms(-1500), '-1s');
• assert.strictEqual(ms(1500, { long: true }), '2 seconds');
• assert.strictEqual(ms(-1500, { long: true }), '-1 seconds');
• assert.throws(() => ms(NaN), /val is not a non-empty string or a valid number/);
• assert.throws(() => ms(Infinity), /val is not a non-empty string or a valid number/);
• assert.throws(() => ms(''), /val is not a non-empty string or a valid number/);
• assert.strictEqual(ms('invalid-duration'), undefined);
