console.log(str);

let multipleSpaces = "This   has   multiple   spaces.";
console.log(multipleSpaces);

let stringWithSpaces = "   Leading and trailing spaces.   ";
let trimmedString = stringWithSpaces.trim();
console.log(trimmedString); // Outputs: "Leading and trailing spaces."

<p>This&nbsp;&nbsp;&nbsp;is&nbsp;&nbsp;&nbsp;HTML&nbsp;&nbsp;&nbsp;with&nbsp;&nbsp;&nbsp;non-breaking&nbsp;&nbsp;&nbsp;spaces.</p>

.pre-space {
  white-space: pre; /* 保留所有空白符序列，但是正常地进行换行 */
}
