Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, collection, strings, lang, function, objects, numbers etc.
The _.replace() method replace the matches for pattern in string with replacement. This method is based on String#replace.
Syntax:
_.replace(string, pattern, replacement)
Parameters: This method accepts three parameters as mentioned above and described below:
- string: This parameter holds the original string.
- pattern: This parameter holds the pattern string that need to replace.
- replacement: This parameter holds the replacement string.
Return Value: This method returns the modified string.
Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library in the file.
javascript
// Requiring the lodash library const _ = require("lodash");   // Original array var string = _.replace('Stay In', 'In', 'Safe');      // Using the _.replace() method let replace_elem = _.replace(string);   // Printing the output console.log(replace_elem); |
Output:
Stay Safe
Example 2:
javascript
// Requiring the lodash library const _ = require("lodash");   // Original array var num = _.replace('234 56 41', '56 41', '78');       // Using the _.replace() method let replace_elem = _.replace(num);   // Printing the output console.log(replace_elem); |
Output:
234 78
Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
