Lodash _.sub()方法返回所有給定參數的差。
用法:
_.sub( val1, val2, ..., valn );
參數:此方法返回n個值以對它們進行操作_.sub()方法。
返回值:此方法返回所有給定參數的差。
注意:由於它需要安裝lodash.js contrib庫,因此在常規JavaScript中將無法使用。可以使用npm install lodash-contrib -save安裝Lodash.js contrib庫。
範例1:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
var diff = _.sub( 10, 2, 4, 1 );
console.log("The Difference is:", diff);
輸出:
The Difference is:3
範例2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
var diff = _.sub( 10 );
console.log("The Difference is:", diff);
輸出:
The Difference is:10
範例3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
var diff = _.sub( 1, 3, 5, 7, 9, 99, 100 );
console.log("The Difference is:", diff);
輸出:
The Difference is:-222
