In this blog, we will learn how to merge multiple arrays and strings into a single array with Lodash library. We can merge or combine multiple arrays and strings into a single array with Lodash by using the _.concat() method provide by the Lodash library. This method joins two or more strings and it doesn’t change the existing strings/arrays. It returns a new string/array. In that way our original data is not changed.
Merge Multiple Array & String Into One Array
_.concat(string1, string2, …, stringN)
Concatenation with Lodash
const _ = require("lodash"); const str = 70; const arr1 = ; const arr2 = [40, 35]; const arr3 = [] const final_arr = _.concat(str, arr1, arr2, arr3);
The _.concat() method takes all the arrays and other items as parameters and combines them together to generate the output (that’s a new array).
Concatenation with JS
<script> let text1 = "Hello"; let text2 = "world!"; let text3 = "Have a nice day!"; let result = text1.concat(" ", text2, " ", text3); console.log(result); </script>
