我在一门课程中纠结于这段代码--它应该只擦除每个字符的第一个示例，但是我的循环擦除了所有示例。我想在测试后从toerase中删除示例，然后在运行后重建，但似乎过于复杂。我如何使用内置的替换函数来解决这个问题？

disappearString = (myString, toErase) => {
    // Place your code here
    
    //let to earase an array of string to disappear
    var toErase = stringToDisappear.split('');

    //toErase = toErase.join(||');//join array with ||(or) didn't work - binned this idea

    //console.log (toErase); //checking its come as an array

        let result = ""; //define result as empty
    //loop to erase each instance - but for f**s sake I don't want to do that, just remove the first instance"!
      for (let i = 0; i < myString.length; i++) {
        let letter = myString[i]; //declare letter
        if (!toErase.includes(letter) ) { //check if letter is the same as any of toerase
          result += myString[i]; //if letter is not in toerase print it.
      
        }
      };
      return result;
    };
