Replace characters in string array Javascript

Question

I have defined and populated an array called vertices. I am able to print the output to the JavaScript console as below:

["v 2.11733 0.0204144 1.0852", "v 2.12303 0.0131256 1.08902", "v 2.12307 0.0131326 1.10733" ...etc. ]

However I wish to remove the 'v' character from each element. I have tried using the .replace() function as below:

var x;
for(x = 0; x < 10; x++)
{
    vertices[x].replace('v ', '');
}

Upon printing the array to the console after this code I see the same output as before, with the 'v's still present.

Could anyone tell me how to solve this?

Solution 1

Strings are immutable, so you just have to re-assign their value:

vertices[x] = vertices[x].replace('v ', '');

Solution 2

Should be

vertices[x]=vertices[x].replace('v ', '');

Because replace returns value, and doesn't change initial string.

Solution 3

vertices[x] = vertices[x].replace('v ', '');
