Question

我正在尝试编写一个js函数，该函数比较两个字符串并返回相似事件的数量。但是我的功能是也考虑重复。例如，两个单词“ state”和“ tall”。理想情况下，它应返回2的计数，但考虑到“状态”中有两个重复的t，它将返回3。谁能帮我这个忙

Answer 2

下次您必须先发布代码，但这对您来说应该有用：

const countSimilarities = (s1, s2) =>
  s1
    .split("")
    .map((char1) => s2.split("").find((char2) => char1 === char2))
    .reduce((acc, c) => (c ? acc + 1 : acc), 0);

Answer 3

可能可以对此进行优化，但这是进行此检查的函数的相当简单的版本。

function matchingLettersCount(s1, s2) {
  const letters1 = [...new Set(s1.split(''))];
  const letters2 = [...new Set(s2.split(''))];
  return letters1.filter(x => letters2.includes(x)).length;
}

console.log(matchingLettersCount('state', 'tall'));

Answer 4

这可以帮助吗？我希望：如果希望区分大小写，请将“ gi”替换为“ g”。

class CustomTooltip extends Component {
  tooltipId = `Tooltip-${this.props.name}-${Math.random().toString(36).substr(2, 5)}`
