i want to convert an array of strings to array of boolean using javascript.
i have an array of strings like below
const data = ["true", "false", "false", "false", "true"]
how can i convert above array of strings to array of booleans like below,
const data = [true, false, false, false, true]
how can i do this using javascript. could someone help me with this? thanks.
You could map the parsed values.
const
data = ["true", "false", "false", "false", "true"],
result = data.map(j => JSON.parse(j));
console.log(result);if you want to save the result into a new variable use map
const data = ["true", "false", "false", "false", "true"]
const result = data.map(e => e === 'true')
if you want change the original variable (the variable named "data") use forEach:
data.forEach((e, i) => { data[i] = e === "true" })
Assuming you want to change the existing array instead of generate a new one... Just check to see if each one is "true."
You could use JSON.parse as well, but that's probably overkill if you just have true and false, and it might throw an error if there's anything else in the array.
const data = ["true", "false", "false", "false", "true"];
for(var i=0; i<data.length; i++) data[i] = data[i] === 'true';
console.log(data);
