I want that if i am given a value like 1k then it should be converted to 1000 or 1m to 100000 and so on..
1k - 10000
100k - 100000
1m - 1000000
1b - 1000000000
I have searched a lot on the internet, but I can't find any npm package that can do it as well.
i just want a code solution or a npm package to help me in it.

Answer 1

Maybe you can try this
var thousand = '1k'
var hundredThousand = '100k'
var hundredThousandComa = '13.5k'
var million = '1m'
var billion = '1b'
var arrayFormat = [thousand, hundredThousand, hundredThousandComa, million, billion]
arrayFormat.map((value) => {
var number = value.slice(0, -1)
var last = value.slice(-1)
if (last == 'k') {
console.log(number * 1000)
} else if (last == 'm') {
console.log(number * 1000000)
} else if (last == 'b') {
console.log(number * 1000000000)
}
})

Answer 2

Create a map of units to coefficients.
Parse each input string into its value and unit.
Multiply the value by the corresponding unit's coefficient to get the product.
Example:
const map = {
k: 1e3,
m: 1e6,
b: 1e9,
// etc.
};
const inputs = [
'1k',
'100k',
'1m',
'1b',
];
for (const input of inputs) {
const value = input.slice(0, -1);
const unit = input.slice(-1);
const product = value * map[unit];
console.log(value, unit, product);
}
