I have a matrix of strings that looks like this:
stringMatrix = `
1 0 0
0 1 0
0 0 0
`
I am looking for a way to convert it into a double array: [[1,0,0], [0,1,0], [0,0,1]], is there a more elegant js-y solution to achieve this?
I attempted
matrix = values[0].trim().split('\n');["1 0 0", "0 1 0", "0 0 0"]; I could use a for-loop, but I was hoping for a solution involving lambda expressions or fat arrows.
//plain vanilla javascript
One of the easiest ways is to simply split and then map it.
let stringMatrix = `
1 0 0
0 1 0
0 0 0
`
let result = stringMatrix.trim().split("\n").map( line => line.split(/\s+/).map(Number))
console.log(result)This code snippet will generate a number array as an output by utilizing the split and map functions to process a string matrix containing numerical values.
stringMatrix = `
1 0 0
0 1 0
0 0 0
`;
let result = [];
stringMatrix = stringMatrix.trim().split('\n').map(function(element){
let ret = [];
for(let digit of element.match(/\d/g)){
ret.push(parseInt(digit));
}
return ret;
});
