Lodash _.strContains() Method

Lodash _.strContains() method checks whether the given string contains the searched string or not and returns the corresponding boolean value.

Syntax:

Parameters:

• String: This method takes String in which search string is to be searched.
• Searched_str: This method takes a string to be searched.

Note: This will not work in normal JavaScript because it requires the lodash.js contrib library to be installed. Lodash.js contrib library can be installed using npm install lodash-contrib –save.

Example 1: In this example, we are checking whether the "Geeks" is present in the given "GeeksforGeeks" or not.

// Defining lodash contrib variable 
let _ = require('lodash-contrib');

let bool = _.strContains("GeeksforGeeks", "Geeks");

console.log("The String contains the "
    + "searched String : ", bool);

Output:

The String contains the searched String : true

Example 2: In this example, we are checking whether the "d" is present in the given "abd" or not.

// Defining lodash contrib variable 
let _ = require('lodash-contrib');

let bool = _.strContains("abc", "d");

console.log("The String contains the "
    + "searched String : ", bool);

Output:

The String contains the searched String : false

Example 3: In this example, we are checking whether the "a" is present in the given "abc" or not.

// Defining lodash contrib variable 
let _ = require('lodash-contrib');

let bool = _.strContains("abc", "a");

console.log("The String contains the "
    + "searched String : ", bool);

Output:
