Lodash _.isEqual()方法p在兩個值之間進行深入比較,以確定它們是否等效。此方法支持比較數組,數組緩衝區,布爾值,日期對象,Map,數字,對象,正則表達式,集合,字符串,符號和類型化數組。
用法:
_.isEqual( value1, value2)
參數:此方法接受上麵提到和下麵描述的兩個參數:
- value1:要檢查的value1。
- value2:要檢查的value2。
返回值:此方法返回一個布爾值(如果兩個值相等,則返回true,否則返回false)。
範例1:
Javascript
// Defining Lodash variable
const _ = require('lodash');
var val1 = { "a":"gfg" };
var val2 = { "a":"gfg" };
// Checking for Equal Value
console.log("The Values are Equal:"
+_.isEqual(val1,val2));
輸出:
The Values are Equal:true
範例2:對於數組:
Javascript
// Defining Lodash variable
const _ = require('lodash');
var val1 = [1, 2, 3, 4]
var val2 = [1, 2, 3, 4]
// Checking for Equal Value
console.log("The Values are Equal:"
+_.isEqual(val1,val2));
輸出:
The Values are Equal:true
範例3:對於字符串:
Javascript
// Defining Lodash variable
const _ = require('lodash');
var val1 = "gfg"
var val2 = "gfg"
// Checking for Equal Value
console.log("The Values are Equal:"
+_.isEqual(val1,val2));
輸出:
The Values are Equal:true
範例4:對於數字:
Javascript
// Defining Lodash variable
const _ = require('lodash');
var val1 = 1
var val2 = 1
// Checking for Equal Value
console.log("The Values are Equal:"
+_.isEqual(val1,val2));
輸出:
The Values are Equal:true
範例5:
Javascript
// Defining Lodash variable
const _ = require('lodash');
var val1 = 222
var val2 = 323
// Checking for Equal Value
console.log("The Values are Equal:"
+_.isEqual(val1,val2));
輸出:
The Values are Equal:false
