How do I replace a character in a string with regex and javascript?

I have a string:

let y = ".1875 X 7.00 X 8.800";

I would like to return this as an array of 3 numbers: 0.1875, 7.00, 8.800

I need to convert .1875 into 0.1875, however you can’t just target the first character because what if the string is like so:

let x = "7.00 X .1875 X 8.800";

or another difficult example

let y = ".50" x 1.25" x 7.125" will make one part"

This is my attempt so far:

let numbers = x.match(/(\d*\.)?\d+/g)
numbers.map(n => parseFloat(n))


var thickness = numbers[0]
var width = numbers[1]
var length = numbers[2]


if(thickness.charAt(0) == '.'){

    let stringA = numbers[0].match(/^(\.)/g)
    let stringB = "0"

    thickness.replace(stringA, stringB)
    console.log(thickness)}

else {
     alert('failure');
}

I can’t seem to replace the . in .1875 to 0.1875, any help much appreciated!

>Solution :

Here is one way to do so using regex:

let x = "7.00 X .1875 X 8.800";

const pattern = /\d*\.?\d+/g;

const numbers = [...x.matchAll(pattern)].map(Number);
console.log(numbers);

• \d*: Matches any digit between 0 and unlimited times, as much as possible.
• \.?: Optionally matches ..
• \d+: Matches any digit between 1 and unlimited times, as much as possible.
