rated 0 times [ 3] [ 7] / answers: 1 / hits: 119478 / 12 Years ago, tue, february 12, 2013, 12:00:00

I want to convert a 2D JavaScript array to a 1D array, so that each element of the 2D array will be concatenated into a single 1D array.

Here, I'm trying to convert arrToConvert to a 1D array.

var arrToConvert = [[0,0,1],[2,3,3],[4,4,5]];



console.log(get1DArray(arrToConvert)); //print the converted array



function get1DArray(2dArr){

    //concatenate each element of the input into a 1D array, and return the output

    //what would be the best way to implement this function?

}

Try .concat():

var arrToConvert = [[0,0,1],[2,3,3],[4,4,5]];

var newArr = [];





for(var i = 0; i < arrToConvert.length; i++)

{

    newArr = newArr.concat(arrToConvert[i]);

}



console.log(newArr);
