从由特殊字符分隔的字符串数组中删除特定后缀

function removeSuffixFromSeparatedStrings(strings, separator, suffix) {
  let result = [];
  
  for (let i = 0; i < strings.length; i++) {
    let separatedStrings = strings[i].split(separator);
    let modifiedStrings = [];
    
    for (let j = 0; j < separatedStrings.length; j++) {
      let currentString = separatedStrings[j];
      
      if (currentString.endsWith(suffix)) {
        currentString = currentString.slice(0, -suffix.length);
      }
      
      modifiedStrings.push(currentString);
    }
    
    result.push(modifiedStrings.join(separator));
  }
  
  return result;
}

// 示例用法
let strings = ["abc_def_ghi", "jkl_mno_pqr", "stu_vwx_yz"];
let separator = "_";
let suffix = "yz";

let modifiedStrings = removeSuffixFromSeparatedStrings(strings, separator, suffix);
console.log(modifiedStrings);
