Replace a string in a string array on Angular2

Question

I have a string array with strings like age ,gender,nationality. Need to replace age to agexxxx. So is there any method to replace a string in string array on angular?

this.segment=['age','Nationality','gender'];

Try this ['age','Nationality','gender'].map(w => w === 'age' ? 'agexxxx' : w); If you want to modify the existing array, you can use forEach instead of map. — Hassan Imam

Here you go :

var segment=['age','Nationality','gender'];

var changed = segment.map(seg => seg.replace('age', 'agexx') );


console.log('Original --->' ,segment);
console.log('Changed --->' ,changed);

Use:

for(var i=0; i < this.segment.length; i++) {
 this.segment[i] = this.segment[i].replace('age', 'agexx');
}

let a = ['age','hello','world']
a.splice(0, 1,'agexxx');
alert(a)

reference : Array.prototype.splice
