} var Geeks = {
name: "GeeksforGeeks" ,
about: "Computer Science Portal for Geeks" ,
fun: _.methodize(gfgFunc)
}; console.log(Geeks.fun()) |
Output:
GeeksforGeeks : Computer Science Portal for Geeks
Example 2:
// Defining lodash contrib variable var _ = require( 'lodash-contrib' );
function gfgFunc (obj) {
return "Geeks" ;
} fun= _.methodize(gfgFunc) console.log(fun()) |
Output:
