slice的使用

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>023</title>
</head>
<body>
    
</body>
<script type="text/javascript">
var charSets = ["ab","bb","cd","ab","cc","ab","dd","ab"];
var domestic = charSets.slice(4,7);
console.log(domestic);

var mArray = [];
mArray[0] = ['apple','pear'];
mArray[1] = ['strawberry','lemon'];
mArray[2] = ['lime','peach','berry'];

var nArray = mArray.slice(1,2);
console.log(mArray[1]);
console.log(nArray);

nArray[0][0] = 'raspberry';
console.log(nArray[0]);
console.log(mArray[1]);
</script>
