Lodash _.result() method is used to return the resolved values. If the resolved value is a function then it invoked with the this binding of its parent object. It is almost the same as _.get() function.
Syntax:
_.result( object, path, defaultValue )
Parameters:
This method accepts three parameters as mentioned above and described below:
- object: It is the object that is queried.
- paths: It is a string or array of the paths of the property to resolve.
- defaultValue: It is the value returned for undefined resolved values. It is an optional value.
Return Value:
This method returns the resolved value.
Example 1: In this example, the code uses the Lodash library to access nested property values and invoke a constant function using the _.result
method.
Javascript
const _ = require( "lodash" );
let obj =
{ 'x' : [{ 'y' : {
'z1' : 6, 'z2' : _.constant(9) } }]
};
console.log(_.result(obj, 'x[0].y.z1' ));
console.log(_.result(obj, 'x[0].y.z2' ));
|
Output:
6
9
Example 2: In this example, the code uses the Lodash library to access nested properties and provide default values using the _.result
method.
Javascript
const _ = require( "lodash" );
let obj =
{ 'x' : [{ 'y' : {
'z1' : 3, 'z2' : _.constant(4) } }]
};
console.log(
_.result(obj, 'x[0].y.z3' ,
'default' )
);
console.log(
_.result(obj, 'x[0].y.z3' ,
_.constant( 'new-default' ))
);
|
Output:
'default'
'new-default'
