How to add two arrays into a new array in JavaScript?
Let’s say the following is our first array −
var firstArray=["John","David","Bob","Mike"];
Following is our second array −
var secondArray=["Chris","Adam","James","Carol"];
To add the above two arrays into a new array, use concat().
Example
Following is the code −
var firstArray=["John","David","Bob","Mike"];
var secondArray=["Chris","Adam","James","Carol"];
var thirdArray=firstArray.concat(secondArray);
console.log("First Array value=");
console.log(firstArray);
console.log("Second Array value=");
console.log(secondArray);
console.log("Third Array value=");
console.log(thirdArray);To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo249.js.
Output
This will produce the following output on console −
PS C:\Users\Amit\javascript-code> node demo249.js First Array value= [ 'John', 'David', 'Bob', 'Mike' ] Second Array value= [ 'Chris', 'Adam', 'James', 'Carol' ] Third Array value= [ 'John', 'David', 'Bob', 'Mike', 'Chris', 'Adam', 'James', 'Carol' ]
