I have an array of object as follows
let data = [
{
vertical_name: "CORE",
projects: [
{
name: "Alpha",
id: 187,
current_result: null,
}
]
},
{
vertical_name: "release",
projects: [
{
name: "Beta",
id: 27,
current_result: {
success_percentage: 37,
failure_percentage: 25,
skip_percentage: 36
}
},
{
name: "Charlie",
id: 47,
current_result: {
success_percentage: 37,
failure_percentage: 25,
skip_percentage: 36
}
}
]
}
]
As you can see current_result is null at one place. So i have to modify data to show that current_result is not tested. So in this case, instead of showing null, i want to show as follows. not_tested is 100 and skip, failure and success percentage is 0 in this case.
current_result: {
success_percentage: 0,
failure_percentage: 0,
skip_percentage: 0,
not_tested: 100
}
Also on other values of current_result, since it is not null and has success, failure and skip values, not_tested should be 0 for this.
The final result should look something like this. can someone please let me know how to achieve this as it is slightly complicated for me to come to a definitive answer
result = [
{
vertical_name: "CORE",
projects: [
{
name: "Alpha",
id: 187,
current_result: {
success_percentage: 0,
failure_percentage: 0,
skip_percentage: 0,
not_tested: 100
}
}
]
},
{
vertical_name: "release",
projects: [
{
name: "Beta",
id: 27,
current_result: {
success_percentage: 37,
failure_percentage: 25,
skip_percentage: 36,
not_tested: 0
}
},
{
name: "Charlie",
id: 47,
current_result: {
success_percentage: 37,
failure_percentage: 25,
skip_percentage: 36,
not_tested: 0
}
}
]
}
]
You could loop into data's projects array and insert keys you want in this way:
let data = [ { vertical_name: "CORE", projects: [ { name: "Alpha", id: 187, current_result: null, } ] }, { vertical_name: "release", projects: [ { name: "Beta", id: 27, current_result: { success_percentage: 37, failure_percentage: 25, skip_percentage: 36 } }, { name: "Charlie", id: 47, current_result: { success_percentage: 37, failure_percentage: 25, skip_percentage: 36 } } ] } ]
data.forEach(dat => {
dat.projects.forEach(prj => {
if (!prj.current_result) {
prj.current_result = {
success_percentage: 0,
failure_percentage: 0,
skip_percentage: 0,
not_tested: 100
};
}
else {
prj.current_result.not_tested = 0;
}
})
})
console.log(data)You can filter out your result data and assign a default value.
const result = data.map((item) => {
const projects = item.projects.map((project) => {
if (!project?.current_result) {
return {
...project,
current_result: {
success_percentage: 0,
failure_percentage: 0,
skip_percentage: 0,
not_tested: 100,
},
};
} else {
return project;
}
});
console.log(result)
Using Array#map without mutating the original data
const data = [{"vertical_name":"CORE","projects":[{"name":"Alpha","id":187,"current_result":null}]},{"vertical_name":"release","projects":[{"name":"Beta","id":27,"current_result":{"success_percentage":37,"failure_percentage":25,"skip_percentage":36}},{"name":"Charlie","id":47,"current_result":{"success_percentage":37,"failure_percentage":25,"skip_percentage":36}}]}];
const formatted = data.map(item => Object.assign(item, {
projects: item.projects.map(project => {
if (project.current_result === null) {
project.current_result = {
success_percentage: 0,
failure_percentage: 0,
skip_percentage: 0,
not_tested: 100
};
} else project.current_result.not_tested = 0;
return project;
})
}));
console.log(formatted);
